Qt Version: 5.15.3
Frameworks Version: 5.92.0
Operating System: Linux 5.13.0-40-generic x86_64
Windowing System: X11
Distribution: Ubuntu 22.04 LTS
DrKonqi: 5.24.4 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
I was typing in konversation IRC and then kwin just crashed randomly.
I don't know why but I have all the debug symbols installed so maybe that will help troubleshoot this further.
There was nothing noticeable or intentional that seemed to have crashed kwin, it was just random. Bizarre.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: KWin (kwin_x11), signal: Aborted
