-- Information about the crash:
KWin5 crashes when disabling Fullscreen mode in Subnautica from Steam.

Constantly reproducible. If using Proton, was using Proton Experimental at the time when 8.0-4 was the latest stable release of Proton. Relevant configuration in Options > General of Subnautica.

Note that this a reproduction of the crash depicted at https://bugs.kde.org/show_bug.cgi?id=270002#c12 (do not mark this bug a duplicate bug of that, obviously - visit it if you're confused).

The crash can be reproduced every time.
