Debug log

SUMMARY
When using Polonium (Automatic tiling manager) kwin_wayland crashes sometimes just by clicking windows
Other times resizing windows quickly (or just randomly) causes this issue

STEPS TO REPRODUCE
1. Have a few windows tiled on one monitor
2. Meta + Right while moving the mouse around (Just to spam resizing of different windows)

OBSERVED RESULT
KWin crashes after about 3 seconds

EXPECTED RESULT
No crash

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Arch
(available in About System)
KDE Plasma Version:  6.0.0
KDE Frameworks Version: 6.0.0
Qt Version: 6.6.2

yep pressing meta+right on the left hand window on my screen also guarantees a crash for me, interestingly pressing meta+left on the right hand window does nothing, but i'm not sure if that's relevant to kwin or just a polonium bug
