The crash happens when sending a key event, not sure how a crash could occur at that point *** This bug has been marked as a duplicate of bug 472922 *** I seem to have a similar problem. It doesn't happen frequently, but usually I'm not doing anything. I remember coming back from getting a drink and both monitors went black and firefox crash handler popped up. All of the Qt apps survived though, so yay for that. I tried looking for a cordump with coredumpctl, but it says unavailable for kwin. Apps like dolphin or kate are available, but not kwin_wayland. I tried attaching to the process, but ran into some kind of permission issue. I'm unsure of how to get any usable logs. Please advise on how to do so. Created attachment 167873 [details]
kwin crash log
kwin_wayland seems to crash once a day for me. Usually I am not doing anything. I've had it happen a few times when I wasn't even home. I followed the instructions on the kde developer website and managed to get a log with gdb which I will attach now.
If my problem is a different issue, then let me know to file a different bug report. Just wanted to add my system details: Operating System: EndeavourOS KDE Plasma Version: 6.0.2 KDE Frameworks Version: 6.0.0 Qt Version: 6.6.2 Kernel Version: 6.7.9-zen1-1-zen (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 5800X 8-Core Processor Memory: 62.7 GiB of RAM Graphics Processor: NVIDIA GeForce RTX 3080/PCIe/SSE2 Manufacturer: Micro-Star International Co., Ltd.

Operating System: NixOS 23.11 KDE Plasma Version: 5.27.11 KDE Frameworks Version: 5.113.0 Qt Version: 5.15.12 Kernel Version: 6.1.90 (64-bit) Graphics Platform: Wayland Processors: 12 × AMD Ryzen 5 7640U w/ Radeon 760M Graphics Memory: 60.7 GiB of RAM Graphics Processor: AMD Radeon Graphics This crash has been happening to me multiple times a day some days for about three months now. does anyone have any advice to root-cause and debug this? I am prepared to patch and compile kwayland and kwin_wayland at least from source, and can decently printf debug, but don't really know much about how wayland works to really have a conceptual understanding of what is happening on this codepath. But it happens most regularly when i press ctrl-backspace, which i do in both of my primary applications emacs and firefox, as a muscle memory. It happened while I was drafting this comment.

SUMMARY Kwin_wayland crashes semi-randomly whenever I have Blender (4.0.2), GIMP (2.10.36) and Firefox (122.0) running at the same time. I think this time, it happened when trying to open ArmorPaint, but the reason can be as trivial when clicking in Blender or Alt+Tabbing or else.
