I was not able to create specific circumstances when it happens but it happens when you have multiple windows open and the tiler is adjusting the window locations. I was able to create a semi-reproducible environment with kde-builder tests. STEPS TO REPRODUCE 1. Use the Krohnkite Kwin script 2. Open two dolphin windows on the same screen 3. Run `kde-builder --no-src --no-include-dependencies kio --run-tests` (assuming you have precompiled the dependencies) 4. Wait for the tests to start jerking the windows around OBSERVED RESULT kwin_wayland crashes most of the time EXPECTED RESULT No crash SOFTWARE/OS VERSIONS Linux: Arch Linux KDE Plasma Version: 6.1.4 KDE Frameworks Version: 6.5.0 Qt Version: 6.7.2 2353127 1 antti.savo 2024-09-11 20:30:13 +0000 I found another way to reliably reproduce. Use the vesktop discord client, un-tile the vesktop window, go into a voice channel and start a screen share. Kwin will crash when you select which monitor you want to share. 2360111 2 bug-janitor 2024-09-26 14:02:31 +0000 A possibly relevant merge request was started @ https://invent.kde.org/plasma/kwin/-/merge_requests/6518 2360130 3 vlad.zahorodnii 2024-09-26 14:15:58 +0000 (In reply to Antti Savolainen from comment #1) > I found another way to reliably reproduce.

Can you also report this issue to krohnkite developers? It resizes closed windows, which what it shouldn't do. 2360131 4 antti.savo 2024-09-26 14:16:58 +0000 Will do. 2360137 5 vlad.zahorodnii 2024-09-26 14:48:49 +0000 Git commit f339c4281f6c0513e1b847599f28f750eec01923 by Vlad Zahorodnii. Committed on 26/09/2024 at 14:41. Pushed by vladz into branch 'master'. Guard closed windows against move and resize operations A closed window cannot react to new geometry, also requesting new geometry can involve accessing resources that are gone/deleted now. Scripts trying to move or resize a closed window is a bug though.
