Application: kwin_x11 (5.27.5) Qt Version: 5.15.8 Frameworks Version: 5.103.0 Operating System: Linux 6.1.0-26-amd64 x86_64 Windowing System: X11 Distribution: Debian GNU/Linux 12 (bookworm) DrKonqi: 5.27.5 [CoredumpBackend] -- Information about the crash: While the 'KDE Partition Manager' is running(the tab that appear when you press apply) focus it and move it around then change to another tab and move it around will cause the crash. Tried and crashed with Steam, Fire fox, The KDE Crash Handler, Dolphin, Konsole, Dragon player, System Settings, KDE Partition Manager, Discover, LibreOffice, Ark and could be every tab, but that's all I tried and crashed. The crash can be reproduced every time. -- Backtrace: Application: KWin (kwin_x11), signal: Segmentation fault PID: 23671 (kwin_x11) UID: 1000 (underscore) GID: 1000 (underscore) Signal: 11 (SEGV) Timestamp: Thu 2024-10-10 15:35:18 +07 (1min 12s 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 (underscore) Boot ID: 5ab4198aa50b414da5eed54caa999eb8 Machine ID: 6d2a2f29fdd44b8da416ad9cd9966b9f Hostname: CutieGooberUnderscore Storage: /var/lib/systemd/coredump/core.kwin_x11.1000.5ab4198aa50b414da5eed54caa999eb8.23671.1728549318000000.zst (present) Size on Disk: 6.1M Message: Process 23671 (kwin_x11) of user 1000 dumped core.
