[BUG]: The main window spontaneously moves up when switching full-screen / window mode

[VladimirVSC]

Describe the Bug

As it is said in the description, the main window moves up after every full-screen - window transition. My system (if necessary): Core-I5 12500, 16 Gb Ram, RTX 3060 Ti (525.125.06 driver).

The main window must stay where it was initially placed to.

Are you using Wayland? This is likely not our bug - we don't move the window, but we do hide and re-show it on fullscreen transition, so it may be your window manager/compositor doing it.

Okay, dug into it, it's sadly invalid.

Under Wayland, the compositor decides where the window reopens, not the application. Flawed protocol by design. See https://gitlab.freedesktop.org/wayland/wayland-protocols/-/issues/72. So it ends up reopening in a fixed position under kwin, and slowly moves down the screen under GNOME.

Under xorg, on kwin, it positions as expected. But under Wayland, it opens in the original position that it decided to put PCSX2 in on startup (again, because our "restore window position" code doesn't work, because Wayland doesn't allow it).

So yes. Not our bug.
