Application: kwin_x11 (5.27.10) Qt Version: 5.15.10 Frameworks Version: 5.107.0 Operating System: Linux 6.6.13-amd64 x86_64 Windowing System: X11 Distribution: Debian GNU/Linux trixie/sid DrKonqi: 5.27.10 [CoredumpBackend] -- Information about the crash: I alt+tab through several firefox windows and pycharm windows. The tabbing was buggy and the windows didn't show a preview. KWin crashed then 2 times in a row when alt+tabbing. The reporter is unsure if this crash is reproducible. -- Backtrace: Application: KWin (kwin_x11), signal: Segmentation fault PID: 1942 (kwin_x11) UID: 1000 (johannes) GID: 1000 (johannes) Signal: 11 (SEGV) Timestamp: Sat 2024-02-10 22:55:52 CET (46s ago) Command Line: /usr/bin/kwin_x11 --replace Executable: /usr/bin/kwin_x11 Control Group: /user.slice/user-1000.slice/user@1000.service/session.slice/plasma-kwin_x11.service Unit: user@1000.service User Unit: plasma-kwin_x11.service Slice: user-1000.slice Owner UID: 1000 (johannes) Boot ID: 5ed1274be3a84b2eb136b4b1fc514515 Machine ID: 7022a249a2a04e5688393321af5fbac6 Hostname: johannes-debian Storage: /var/lib/systemd/coredump/core.kwin_x11.1000.5ed1274be3a84b2eb136b4b1fc514515.1942.1707602152000000.zst (present) Size on Disk: 7.2M Message: Process 1942 (kwin_x11) of user 1000 dumped core.
