// TODO: If no compositor is running but a fullscreen application is running (on the focused monitor)
// then use xcomposite to get that window as a texture and use that as a background because then the background can update.
// That case can also happen when using a compositor but when the compositor gets turned off when running a fullscreen application.
// This can also happen after this overlay has started, in which case we want to update the background capture method.
// TODO: Make keyboard controllable for steam deck (and other controllers).
// TODO: Keep track of gpu screen recorder run by other programs to not allow recording at the same time, or something.
// TODO: Remove gpu-screen-recorder-overlay-daemon and handle that alt+z global hotkey here instead, to show/hide the window
// without restaring the program. Or make the daemon handle gpu screen recorder program state and pass that to the overlay.
// TODO: Add systray by using org.kde.StatusNotifierWatcher/etc dbus directly.
// TODO: Dont allow replay and record/stream at the same time. If we want to allow that then do that in gpu screen recorder instead
// to make it more efficient by doing record/replay/stream with the same encoded packets.
// TODO: Make sure the overlay always stays on top. Test with starting the overlay and then opening youtube in fullscreen.
