SUMMARY
KWin crashes when playing a specifically crafted video file using mpv ( https://mpv.io/ ).

STEPS TO REPRODUCE
1. Play the attached video file with mpv -vo gpu (default) or -vo x11. Other players that show only the video without additional controls might work too but it is not guaranteed (e.g. mpv with -vo sdl does not reproduce the bug).

OBSERVED RESULT
KWin goes bye bye.

EXPECTED RESULT
KWin survives whatever window properties/dimensions mpv sets.
