Faster run_command_timeout

The "normalWindow" check was added "just in case", since for Spectacle it's also true. Unfortunately it seems there's literally no other reliable way of checking for Spectacle windows other than hardcoding a check for its resourceClass...

 # GPU Screen Recorder UI
 A fullscreen overlay UI for [GPU Screen Recorder](https://git.dec05eba.com/gpu-screen-recorder/about/) in the style of ShadowPlay.\
-The application is currently primarly designed for X11 but it can run on Wayland as well through XWayland, with some caveats because of Wayland limitations.\
-Note: This software is still in early alpha. Expect bugs, and please report any if you experience them. Some are already known, but it doesn't hurt to report them anyways.\
-You can report an issue by emailing the issue to dec05eba@protonmail.com.
-
-# Usage
-Run `gsr-ui` and press `Left Alt+Z` to show/hide the UI. You can start the overlay UI at system startup by running `systemctl enable --now --user gpu-screen-recorder-ui`.
-There is also an option in the settings to enable/disable starting the program on system startup. This option only works on systems that use systemd.
-You have to manually add `gsr-ui` to system startup on systems that uses another init system.\
-A program called `gsr-ui-cli` is also installed when installing this software. This can be used to remotely control the UI. Run `gsr-ui-cli --help` to list the available commands.

 # Installation
-If you are using an Arch Linux based distro then you can find gpu screen recorder ui on aur under the name gpu-screen-recorder-ui (`yay -S gpu-screen-recorder-ui`).\
+If you are running an Arch Linux based distro then you can find gpu screen recorder ui in the official repositories under the name gpu-screen-recorder-ui (`sudo pacman -S gpu-screen-recorder-ui`).\
 If you are running another distro then you can run `sudo ./install.sh`, but you need to manually install the dependencies, as described below.\
-You can also install gpu screen recorder (the gtk gui version) from [flathub](https://flathub.org/apps/details/com.dec05eba.gpu_screen_recorder). This flatpak includes both this UI and gpu-screen-recorder so no need to install that first.
+You can also install gpu screen recorder from [flathub](https://flathub.org/apps/details/com.dec05eba.gpu_screen_recorder) which includes this UI.
+
+# Usage
+Start the program by running `gsr-ui` or clicking on `GPU Screen Recorder` on your desktop or in your application launcher.
+Press `Left Alt+Z` to show/hide the UI. Go into the settings (the icon on the right) to view all of the different hotkeys configured.\
+If you want the program to start on system startup and have it running in the background where it can be controlled with the hotkeys at any time
+then open the UI and go into the settings (the icon on the right) and enable "Start program on system startup?".\
+The application will be added to `~/.config/autostart/gpu-screen-recorder-ui.desktop`. This will be launched automatically when you use a desktop environment,
+but if you use a minimal window manager then you need to use a XDG autostart program such as `dex`, or launch the program manually from your window manager startup script.\
+A program called `gsr-ui-cli` is also installed when installing this software. This can be used to remotely control the UI. Run `gsr-ui-cli --help` to list the available commands.

 ## Program behavior notes
-At the moment different keyboard layouts are not supported. The physical layout of keys are used for global hotkeys. If your Z and Y keys are swapped for example then you need to press Left Alt+Y instead of Left Alt+Z to open/hide the UI.\
-If you experience this issue then please email dec05eba@protonmail.com to get it fixed.\
-This program has to grab all keyboards and create a virtual keyboard (`gsr-ui virtual keyboard`) to make global hotkeys work on all Wayland compositors.
-This might cause issues for you if you use input remapping software. To workaround this you can go into settings and select "Only grab virtual devices"
+By default this program has to grab all keyboards and creates a virtual keyboard (`gsr-ui virtual keyboard`) to make global hotkeys work on all Wayland compositors.\
+This might cause issues for you if you use keyboard remapping software. To workaround this you can go into settings and select "Yes, but only grab virtual devices" or "Yes, but don't grab devices".\
+If you use keyboard remapping software such as keyd then make sure to make it ignore "gsr-ui virtual keyboard" (dec0:5eba device id), otherwise your keyboard can get locked
+as gpu screen recorder tries to grab keys and keyd grabs gpu screen recorder, leading to a lock.\
+If you are stuck in such a lock where you cant press and keyboard keys you can press (left) ctrl+shift+alt+esc to close gpu screen recorder and remove it from system startup.

+# FAQ
+## I get an error when trying to start the gpu-screen-recorder-ui.service systemd service
+If you have previously used the flatpak version of GPU Screen Recorder with the new UI then the non-flatpak version of the systemd service will conflict with that. Run `gsr-ui` to fix that.
+## I use a non-qwerty keyboard layout and I have an issue with incorrect keys registered in the software
+This is a KDE Plasma Wayland issue. Use `setxkbmap <language>` command, for example `setxkbmap se` to make sure X11 applications (such as this one) gets updated to use your languages keyboard layout.
+## "Save to clipboard" option doesn't work for screenshots
+Some Wayland compositors don't support copying images on the clipboard between X11 and Wayland applications. GPU Screen Recorder UI is an X11 application. It can't be done properly on Wayland
+since Wayland doesn't support a non-focused application from setting the clipboard, so it can't work with GPU Screen Recorder hotkey usage. Use X11 if you want a functioning desktop.
+## The controller hotkey and steam overlap (home button brings up steam overlay)
+You can either disable the steam overlay or in steam click Steam->Settings->Controller and then click "Begin Test" under "Test Device Inputs". Click on "Setup Device Inputs" and configure controller buttons there and when you get to the home button press X to unbind it from steam.
+## The UI looks messed up on my Wayland system
+Wayland doesn't support GPU Screen Recorder UI properly. Some Wayland environments can display GPU Screen Recorder UI pretty well (such as KDE Plasma and Gnome) while others cannot (such as Hyprland and Niri).
+This is an issue in Wayland and it may be the case that it will never be fixed. Use X11 if you experience issues.

+
+Check if "modprobe uinput" is needed on some systems (old fedora?).
+
+Add recording timer to see duration of recording/streaming.
+
+Make folder with window name work when using gamescope. Gamescope runs x11 itself so to get the window name inside that we have to connect to the gamescope X11 server (DISPLAY=:1 on x11 and DISPLAY=:2 on wayland, but not always).
+    Detect if the window is gamescope automatically (WM_CLASS = "gamescope") and get the x11 display automatically and connect to it to get the application its running.
+    This seems to only be an issue on wayland? the window title of the gamescope/steam bigpicture mode is the title of the game on x11, so it works automatically on x11.
+
+When clicking on current directory in file manager show a dropdown menu where you can select common directories (HOME, Videos, Downloads and mounted drives) for quick navigation. Maybe even button to search.
+
+Maybe change gsr-ui startup retry time in the systemd service, from 5 seconds to 2 seconds.
+
+Make it possible to take a screenshot through a button in the ui instead of having to use hotkey.
+
+Handle failing to save a replay. gsr should output "failed to save replay, or something like that" to make it possible to detect that.
+
+Dont allow saving replay while a replay save is in progress.
+
+Make input work with cjk input systems (such as fcitx).
+
+System startup option should also support runit and some other init systems, not only soystemd.
+
+Use x11 shm instead of XGetImage (https://stackoverflow.com/questions/43442675/how-to-use-xshmgetimage-and-xshmputimage).
+
+Do xi grab for keys as well. Otherwise the ui cant be used for keyboard input if a program has grabbed the keyboard, and there could possibly be a game that grabs the keyboard as well.
+
+Make inactive buttons gray (in dropdown boxes and in the front page with save, etc when replay is not running).
+
+Add option to do screen-direct recording. But make it clear that it should not be used, except for gsync on x11 nvidia.
+
+Add systray for recording status.
+
+Verify if cursor tracker monitor name is always correct. It uses the wayland monitor name for recording, but gpu screen recorder uses a custom name created from the drm connector name.
+
+Notification with the focused monitor (with CursorTrackerWayland) assumes that the x11 monitor name is the same as the drm monitor name. Same for find_monitor_by_name.
+
+If CursorTrackerWayland fails then fallback to getting focused monitor by window creation trick. Need to take into consideration prime laptop with dGPU that controls external monitors which cant be captured (different /dev/dri/card device).
+    Maybe automatically switch to recording with the device that controls the monitor.
+    In that case also add all monitors available to capture in the capture list and automatically choose the gpu that controls the monitor.
+
+Support cjk font. Use fc-match to find the location of the font. This also works in flatpak, in which case the fonts are in /run/host/..., where it lists system fonts.
+
+Keyboard layout is incorrect on wayland when using kde plasma keyboard settings to setup multiple keyboards, for example when changing to french.
+    Text input is correct, but hotkey is incorrect.
+    Need to use "setxkbmap fr" as well.
+    This happens only when grabbing keyboard (gsr-global-hotkeys). Same thing is seen with xev.
+
+Getting focused monitor on wayland doesn't work when vrr is enabled. This is because it uses software cursor instead (at least on kde plasma wayland).
+    Right now it falls back to create window & getting window position trick if there is no cursor visible (or a software cursor) and one monitor has vrr enabled.
+        Remove this when linux & wayland supports vrr with hardware cursor plane.
+    Find out another way to get cursor position on wayland.
+    This was fixed in linux 6.11 and in kde plasma in this commit: https://invent.kde.org/plasma/kwin/-/merge_requests/7582/diffs.
+
+Add option to start recording/replay/stream after the notification has disappeared. Show "Starting recording on this monitor in 3 seconds".
+    See if we can use hardware overlay plane instead somehow.
+
+When using wayland for mgl try using wlr-layer-shell and set layer to overlay and keyboard interactivity to exclusive. Do something similar for notifications.
+
+When starting gsr-ui remove any temporary replay disk data that has possibly remained from a crash, by looking for all folders that starts with gsr-replay and end with .gsr, in the replay directory.
+
+Add restart program button, in global settings. It should do almost the same thing as exit program, execept execv gsr-ui.
+
+When gpu screen recorder ui can run as a regular window (and supports tray icon and global shortcut portal) remove gpu screen recorder gtk. Then all error checking needs to be moved from that project to this project.
+    May need support for multi windows, or create a small project to display dialogs.
+
+Add a bug report page that automatically includes system info (make this clear to the user).
+    Do this by sending the report to a custom server that stores that data.
+    The server should limit reports per IP to prevent spam.
+
+Make it possible to change controller hotkeys. Also read from /dev/input/eventN instead of /dev/input/jsN. This is readable for controllers.
+
+Show message that replay/streaming has to be restarted if recording settings are changed while replay/streaming is ongoing.
+
+Support vector graphics. Maybe support svg, rendering it to a texture for better performance.
+
+Support freetype for text rendering. Maybe load freetype as runtime (with dlopen) and use that when available and fallback to stb_freetype if not available.
+
+Show .webm container option. It's currently chosen automatically if vp8/vp9 is chosen. The available containers should automatically switch depending on the video codec.
+
+In settings show audio levels for each audio. Maybe show audio level image beside the audio name in the dropdown box and switch to a different image (have 3-4 different images for each level) depending on the volume.
+
+Only use fake cursor on wayland if the focused x11 window is fullscreen.
+
+Create window as a real overlay window, using layer shell protocol, when possible. This will however minimize windows on floating wms. Check if this can be fixed somehow, or only use layer shell in tiling wms.
+
+Add timeout option for screenshots.
+
+Add a window that shows a warning for wayland users, that wayland doesn't support this software and if they experience issues then they should use x11 instead.
+
+Add a window that shows a warning if gpu video encoding isn't supported.
+
+Disable system notifications when recording. Does the notification dbus interface support pausing notifications?
+
+Disable hotkeys if virtual keyboard is found (either at startup or after running), if grab type if not virtual. Show a notification if that happens that hotkeys have been disabled.
+    Detect if keyboard is locked by listening to gsr-ui virtual keyboard events and if no event is received after pressing a key (when writing to it after receiving input from another keyboard)
+    then remove the keyboard grab and show a message or something.
+        This can happen if the gsr-ui virtual keyboard is grabbed by some other software.
+        Maybe this can be fixed automatically by grabbing gsr-ui virtual keyboard and releasing it just before we write to it and then release it again.
+        But wont keyboard remapping software grab the keyboard first if they detect it quickly?
+            If we fail to grab it because some other software did then dont grab any keyboards nor gsr-ui virtual keyboards, just listen to them.
+
+Add option to not capture cursor in screenshot when doing region/window capture.
+
+Window selection doesn't work when a window is fullscreen on x11.
+
+Make it possible to change replay duration of the "save 1 min" and "save 10 min" by adding them to the replay settings as options.
+
+If replay duration is set below the "save 1 min" or "save 10 min" then gray them out and when hovering over those buttons
+    show a tooltip that says that those buttons cant be used because the replay duration in replay settings is set to a lower value than that (and display the replay duration there).
+
+The UI is unusable on a vertical monitor.
+
+Steam overlay interfers with controller input in gsr ui. Maybe move controller handling the gsr-global-hotkeys to do a grab on the controller, to only give the key input to gsr ui.
+
+For joysticks (gamepads) create a virtual device for each one (/dev/uinput) that has the same vendor, product and name. This is to make sure that it behaves the same way in applications since applications
+    access joysticks directly through /dev/input/eventN or /dev/input/jsN. It needs the same number of buttons and pretend to be a controller of the same time, for example a ps4 controller
+    so that games automatically display ps4 buttons if supported.
+    This also allows us to copy event bits and other data from the device instead of saying we support everything.
+    This should fix the issue of not being able to write to /dev/uinput with ABS_X event bit set.
+    Maybe do this for regular keyboard inputs as well?
+
+Use generic icons for controller input in settings and allow configuring them.
+
+Add option to include game name in file name (video and screenshot). Replace / with space.
+
+Check if the focused window is on top on x11 when choosing to take screenshot or show the window as the background of the overlay.
+
+Convert clipboard image to requested type (from jpg to png for example).
+
+Save clipboard image with wayland on wayland. Some wayland compositors (such as hyprland, budgie and maybe more (wlroots based ones?)) don't support copying clipboard image data from x11 applications to wayland applications.
+    This can be done because retarded wayland only supports setting clipboard when the application has focus. This doesn't work with hotkey screenshot use.
+    This is specifically an issue when using wl_data_device_manager, which is a standard protocol. It can be done when using wlr specific protocol.
+
+When gsr supports pausing recording done in replay/streaming session then add support for that in gsr-ui as well.
+
+Add recording timer when recording to show for how long we have been recording for. Maybe the same for live streaming and replay.
+
+Add option to trim video in the ui. Show a list of all videos recorded so you dont have to navigate to them (maybe add option to manually navigate to a video as well). Maybe use mpv to view it (embedded) in the ui and trim regions (multiple) and ffmpeg command to trim it.
+
+Show the currently recorded capture in the ui, to preview if everything looks ok. This is also good for webcam overlay. Do this when gsr supports rpc, which would also include an option to get a fd to the capture texture.
+
+Show a question mark beside options. When hovering the question mark show a tooltip that explains the options.
+
+Remove all mgl::Clock usage in Overlay. We only need to get the time once per update in Overlay::handle_events. Also get time in other places outside handle_events.
+
+Handle stopping replay/stream when recording is running (show notification that the video is saved and move the video to folder with game name).
+
+Sometimes when opening gpu screen recorder ui gsr-global-hotkeys incorrectly detects that keyboard input is locked.
+
+When running replay for a long time and then stopping it it takes a while. Improve this.
+
+Make it possible to resize webcam box from top left, top right and bottom left as well.
+
+The flatpak version can for some get stuck at shutdown when instant replay is running. It only happens in the flatpak version and only when instant replay is running and it happens always. Manual SIGINT on gsr-ui stops gsr-ui properly, so why does it fail when shutting down the computer when the systemd stop signal is SIGINT? Maybe its related to the flatpak version being launched through gsr-gtk. I cant personally reproduce it.
+
+Redesign the UI to allow capturing multiple video sources. Move webcam to capture sources as well then. Maybe design the UI to work more like obs studio then, where you start recording and then add sources at capture time, with a preview.
+
+Add option to choose video container (either flv or mpegts) for youtube livestreaming.
+
+Get wayland cursor position for region selector, otherwise the start position before the cursor moves is off.
+
+Add option to set preset on nvidia. Use -ffmpeg-video-opts for that.
+
+Webcam resolution list is too long for some people. Fix it by separating resolution and framerate. Sort resolution and framerate from highest to lowest. Add scrollbar for dropdown list. POOP. Add --filesystem=xdg-run/hypr and run the gsr-hyprland-helper directly instead of flatpak spawn or use wlr foreign top level window protocol. Nvidia webcam yuyv capture doesn't seem to work on x11?
+
+Allow settings page to select input capture option/audio, to make sure it doesn't blindly select the default option when the sources aren't temporary available when opening the settings.
+
+Add simple video cutting in the ui.

+  <description summary="Protocol to describe output regions">
+    This protocol aims at describing outputs in a way which is more in line
+    with the concept of an output on desktop oriented systems.
+
+    Some information are more specific to the concept of an output for
+    a desktop oriented system and may not make sense in other applications,
+    such as IVI systems for example.
+
+    Typically, the global compositor space on a desktop system is made of
+    a contiguous or overlapping set of rectangular regions.
+
+    The logical_position and logical_size events defined in this protocol
+    might provide information identical to their counterparts already
+    available from wl_output, in which case the information provided by this
+    protocol should be preferred to their equivalent in wl_output. The goal is
+    to move the desktop specific concepts (such as output location within the
+    global compositor space, etc.) out of the core wl_output protocol.
+
+    Warning! The protocol described in this file is experimental and
+    backward incompatible changes may be made. Backward compatible
+    changes may be added together with the corresponding interface
+    version bump.
+    Backward incompatible changes are done by bumping the version
+    number in the protocol and interface names and resetting the
+    interface version. Once the protocol is to be declared stable,
+    the 'z' prefix and the version number in the protocol and
+    interface names are removed and the interface version number is
+    reset.

+	The logical_size event describes the size of the output in the

+
+	Most regular Wayland clients should not pay attention to the
+	logical size and would rather rely on xdg_shell interfaces.
+
+	Some clients such as Xwayland, however, need this to configure
+	their surfaces in the global compositor space as the compositor
+	may apply a different scale from what is advertised by the output
+	scaling property (to achieve fractional scaling, for example).
+
+	For example, for a wl_output mode 3840×2160 and a scale factor 2:
+
+	- A compositor not scaling the monitor viewport in its compositing space
+	  will advertise a logical size of 3840×2160,
+
+	- A compositor scaling the monitor viewport with scale factor 2 will
+	  advertise a logical size of 1920×1080,
+
+	- A compositor scaling the monitor viewport using a fractional scale of
+	  1.5 will advertise a logical size of 2560×1440.
+
+	For example, for a wl_output mode 1920×1080 and a 90 degree rotation,
+	the compositor will advertise a logical size of 1080x1920.
+
+	The logical_size event is sent after creating an xdg_output
+	(see xdg_output_manager.get_xdg_output) and whenever the logical
+	size of the output changes, either as a result of a change in the
+	applied scale or because of a change in the corresponding output
+	mode(see wl_output.mode) or transform (see wl_output.transform).
