SUMMARY
I am using Polonium to automatically tile my windows with kwin tiling. After a
recent patch it integrated quick tiling into itself. When dragging firefox from
one monitor to another, it crashes kwin_wayland completely. No other program
does this. I assume this happens because it tries to quicktile the window when
dragging it to the edge of a screen. This is also not a 100% repro rate. Some
specific layouts need to happen first which I have not figured out.
STEPS TO REPRODUCE
1. Use polonium to tile windows
2. Get polonium to a certain unknown state
3. Drag a firefox window between two screens
OBSERVED RESULT
kwin_wayland crashes
EXPECTED RESULT
No crash
