Created attachment 162310 [details] backtrace SUMMARY Plasma Wayland session crashes randomly for me. kwin_wayland[1248]: segfault at 160 ip 00007ff88534f136 sp 00007ffd0ea0db30 error 6 in libQt5Qml.so.5.15.11[7ff8852a7000+281000] likely on CPU 15 (core 7, socket 0) I suspect it started after one of the latest minor Qt5 updates, backtrace points into Qt5Qml 5.15.11. STEPS TO REPRODUCE Unknown, crashes appear randomly. OBSERVED RESULT kwin_wayland crashes. EXPECTED RESULT kwin_wayland should not crash.

I have also started to experience random kwin_wayland crashes. So far they have only happened when interacting with the system, such as clicking on a button or moving the mouse, not when the computer is idle. I don’t think there’s a particular application that’s causing the crash.

> in QV4::Object::insertMember Yeah, this is the same thing. I assume there is some cross-thread syncronization issue. Now I have an idea: restrict "kwin_wayland" process affinity to a single CPU core. Maybe it will workaround the issue. I will try that and report back does it still crashes or not.
Nah, affinity does not seem to help, it still crashes.
I had three crashes just today. I will downgrade Qt5 packages to version 5.15.10 and see if the crashes keep happening.
KWin's crashing in the script engine here. Do you have any non-default KWin scripts installed and enabled?
I do have Bismuth (https://github.com/Bismuth-Forge/bismuth) installed and enabled. However if I remember correctly, no crash was during opening/closing a window or any other kind of window manipulation that would engage Bismuth.
Hmm, I do have Bismuth too. Despite the crash was never due to windows manipulation, I kinda see a pattern here. Obviously we need to try go without it.
I'm also using Bismuth 🤔 I've noticed a weird way to prevent crashes: 1. Set up 2 horizontal virtual desktops 2. Open a window for each screen on the first virtual desktop 3. Switch to the 2nd virtual desktop
Well, after a day without Bismuth, I didn't faced any crashes. So yeah, that's it. Not sure is this report should be closed though. Because I doubt that JS code is able to trigger segfaults by its own without actual bugs in the engine.
Isn't Bismuth dead now? I thought Polonium was meant to be its replacement.
Unfortunately Polonium does not support layouts that I use with Bismuth, and Bismuth still works fine for me even with the latest version of KWin. Yesterday I downgraded Qt5 packages to version 5.15.10, and didn’t experience any crash so far either.

(In reply to Nate Graham from comment #12) > Isn't Bismuth dead now? I thought Polonium was meant to be its replacement. Yes, it is effectively abandoned. Polonium still lacks some functionality for me, though I do switched to it currently. The scripts work kinda dirty anyway and always will be. I hope Plasma will continue to improve native tiling so that we don't need them anymore.
Even if Bismuth itself isn't used, a crash a script currently hits is a path a future script could hit. So we need to try to reproduce and follow up.
Update: After four days with the latest Plasma packages but Qt5 packages downgraded to version 5.15.10, I have not experienced a single KWin crash even with Bismuth active, in contrast to 2-3 crashes per day with Qt5 version 5.15.11.

Just want to say that 5.15.12 still triggers the same crash. kwin_wayland[897]: segfault at 230 ip 00007f58b774f0d6 sp 00007ffff01a9f40 error 6 in libQt5Qml.so.5.15.12[7f58b76a7000+281000] likely on CPU 15 (core 7, socket 0)
Have similar issue. Also have bismuth installed 🤔
same happening here, back on 5.27 I had occasional crashes of my wayland session when using bismuth. I'm now using the polonium script on plasma 6.0.1 and the same issue is present except moving any window with the script active almost always immediately crashes the session. I suspect this has a similar root cause.
