Application: kwin_x11 (5.27.5) Qt Version: 5.15.8 Frameworks Version: 5.103.0 Operating System: Linux 6.1.0-10-amd64 x86_64 Windowing System: X11 Distribution: Debian GNU/Linux 12 (bookworm) DrKonqi: 5.27.5 [CoredumpBackend] -- Information about the crash: I use two drives for my system: an NVMe SSD as my root, and a RAID 5 HDD array for my home directory - both formatted with BTRFS. My RAID5 had to re-sync due to a hard reset, which made my entire KDE environment unresponsive, even making logging in via TTY slow, and KWIN repeatedly crashed while I waited for the sync to finish. The system seemed to recover okay after the sync completed (I use MDADM for my raid setups). The crash can be reproduced every time. -- Backtrace: Application: KWin (kwin_x11), signal: Segmentation fault PID: 11911 (kwin_x11) UID: 1000 (thenimas) GID: 1000 (thenimas) Signal: 11 (SEGV) Timestamp: Wed 2023-07-26 14:42:37 EDT (33min 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 (thenimas) Boot ID: 9ae1a56bebfb4e458c4eca7783f1061a Machine ID: ba6842499ed44289bc53c3690dfa1172 Hostname: Jen-PC Storage: /var/lib/systemd/coredump/core.kwin_x11.1000.9ae1a56bebfb4e458c4eca7783f1061a.11911.1690396957000000.zst (present) Size on Disk: 3.2M Message: Process 11911 (kwin_x11) of user 1000 dumped core.

Can you get some logging for the crash, with `journalctl --user-unit plasma-kwin_x11 --boot 0`?
(In reply to Zamundaaa from comment #1) > Can you get some logging for the crash, with `journalctl --user-unit > plasma-kwin_x11 --boot 0`? Unfortunately that's not really possible at this point. The problem resolved itself once my RAID array properly re-synced, and I have since wiped my disk for unrelated reasons. I do have a backup of the filesystem, but running the log command while in chroot simply gave a "-- No entries --" response. I've not had the issue since though, even though my array had to resync at one point again due to user error. What's different about my current setup is my /home directory isn't placed on my array, it's simply another subvolume within BTRFS on my root SSD, and any media directories are manually made into subvolumes on the array instead. I made it this way because I think the root of the problem was the fact that KDE stores a lot of essential files in the user directory that it reads frequently during use. So any time my home directory had some sort of issue, the entire desktop comes to a crawl. I've since recommended against placing the home directory on a hard disk when it comes to BTRFS configuration.
