On kwin_wayland and KDE Plasma, if “Alt+F4” is assigned to “Close Window” shortcut, while the “Quit Shortcuts” option is set to “OFF”, the game window can still be closed by pressing Alt+F4, in both windowed and fullscreen state.

Can confirm with:
Linux 7.1.5-arch1-2; Qt 6.11.1; KDE Plasma 6.7.4; openjdk version "25.0.4" 2026-07-21
I can confirm this issue on Ubuntu 26.04 (GNOME on Wayland) and Linux Mint 22.3 (Cinnamon on X11) as well.
I suspect this is an issue affecting all Linux systems.
If it cannot be easily fixed, a note should be added to tooltips or similar locations stating that “Linux is not supported” before the release.
Can confirm in 26.3-snapshot-7. Not really fixed.
