Full screen/windowed mode toggle leads to black screen on Linux

[heldderarbeit]

Load Core -> ScummVM -> Start Core from windowed Mode: ScummVM GUI is correctly rendered in a window, but if you press F key you get a black screen in fullscreen mode. If you press F again, you get a black screen in a window

Load Core -> ScummVM -> Start Core from fullscreen mode: ScummVM GUI is correctly shown in in fullscreen mode, but if you press F key you get a black screen in a window

If you move the mouse a white rectangle appears inside the black screen.

This is the only core where I've seen this behaviour. At least in Dosbox-pure, the both N64 cores and Snes9x the toggle between fullscreen and windowed mode is working as expected.

System is Arch and RetroArch 1.19.1 from Flathub. This bug occurs on: Gnome X11 Gnome Wayland Plasma X11 Plasma Wayland

Running ScummVM 2.8.1 from Flathub directly does not have this problem (Here toggling between fullscreen and windowed mode with Alt + Enter is working just fine).

I reproduce also this issue on X11 with RA from source.

Does it work if the core is started with the GUI already in full screen mode?

@spleen1981 Yes, the issue also happens when the core is started with the GUI already in full screen mode.
