-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"

 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.

     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.
