Please change the priority to critical. This is very annoying bug.
"Critical" means 100% easily reproducible with data loss. "Crash" is the correct severity here. See https://community.kde.org/Guidelines_and_HOWTOs/Bug_triaging#Severity if there is any remaining confusion about what the severity levels mean If we get many more duplicates though, I'll consider raising the priority to HI and making it a 15-minute bug.

Hi, I think the same than Aleksey Midenkov Its very annoying. I don't know if this bug is crash or critical, but I have this bug for a long time (4- 5 years). I decided to disable drkonqi so I was tired to send reports without answering or fixing. Sometimes plasma restart by itself, other I have to restart with "plasmashell &" PD. Sorry for my english, It's is not my first language

If i remember correctly after reporting the bug, it was a version upgrade (plasma 5.26.x to 5.27.x) dependency issue in fedora kde. When you ran the update before the bug appeared some packages needed replacement and their filenames changed (those were some purely qt related packages) but since their filenames changed you had to accept the replacement of those new dependencies overwriting other existing ones with different filenames. I initially did not accept those as i did not know if it would break my system after I saw the warning in dnf. After that I experienced this bug. After upgrading and overwriting the dependency upon experiencing the bug KDE plasma 5.27.x runs smoothly without those filed bug issues. I hope this helps!
CORRECTION: please scrap the above comment for some reason after logging in i submitted it to the wrong bug number! Above comment was meant for Bug 456531 !!!
No worries.

This is clearly related to Nvidia Drivers / Hardware. Having switched to Radeon, i have not seen segfaults for this codepath in approx 6 months.

Git commit 258cecbf0fab27ee84ad6c43ff3cfe3647215afd by David Edmundson. Committed on 01/09/2023 at 15:32. Pushed by davidedmundson into branch 'master'. windowthumbnail: Cleanup on scene graph invalidation The documentation (https://doc.qt.io/qt-6/qquickitem.html#graphics-resource-handling) states that if we are doing our own low level handling of graphic resources we need to perform cleanup in 3 places: - on item destruction - when an item is removed from the scene (via the virtual releaseResources) - when the scenegraph gets invalidated (via a slot invalidateSceneGraph) We only handled the first two. This would cause a crash if the window thumbnail is showing just an icon instead of a thumbnail and we hit one of the nvidia context loss resets. The atlas texture would be deleted, but we would keep a QSGTexture refernecing something inside that for longer which would linger. I believe we only need the texture provider to reset, but we may as well do it all.
