GZDoom/ZDoom Steals all keyboard input on linux

[naelstrof]

When GZDoom or ZDoom is fullscreen it disables all system-wide keyboard shortcuts like ctrl+alt+delete, volumeup/down keys, workspace switching, and even alt+f4. This causes a serious issue when the application stops responding, as the only solution is to reboot the computer or know kernel-wide shortcuts.

A proposed solution would be to add an option to disable window borders so it can be played in a "fake" fullscreen. Or change the keyboard input method to allow keys to fall through the application.

If the problem happens with ZDoom as well, it would have been better to report on the ZDoom forum.

Yeah I've realized this, thanks.

I've done some research and it's caused by using SDL. The problem does not persist in SDL2.

I'll go post this on the ZDoom forum, excuse me.
