Description vaughanm1@protonmail.com 2023-06-07 19:57:10 UTC 
SUMMARY
Electron windows can crash KWin when moved into a tile when the KWin script Polonium is installed. This script only crashes with electron windows and works fine otherwise.

STEPS TO REPRODUCE
1. Install the Polonium script from the KWin store 
2. Create a new electron window (vscode, slack, discord, etc.)
3. Create some more tiles with konsole and attempt to shift-drag an electron window into a tile

OBSERVED RESULT
The window either does not tile or KWin crashes

EXPECTED RESULT
The script handles the electron window the same as it handles every other type of window and tiles it correctly, or at the very least does not crash

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 6.3.5-zen2-1-zen (64-bit)
(available in About System)
KDE Plasma Version: 5.27.5
KDE Frameworks Version: 5.106.0

not sure if it's relevant, but does this happen with x11 or wayland?
Comment 4 Antti Savolainen 2024-03-20 11:15:32 UTC 
I've tested and reproduced the crash in Wayland. I haven't tried X11. See the duplicate bug.
Comment 5 Antti Savolainen 2024-03-30 17:34:24 UTC 
I believe this has been fixed now. I can no longer cause a crash.
