plasmashell segmentation fault backtrace

SUMMARY
For at least a month I've been observing plasmashell crashes and until a few days ago I was convinced they're related to https://bugs.kde.org/show_bug.cgi?id=492606 (and its duplicates), but even though I'm now running Qt 6.8.1, those crashes still happen. I'm not entirely sure whether this my bug report is related or a duplicate to that closed one, or actually any recent generic-crash entry, and I don't want to mess anything up by posting unrelated backtrace. Other bug reports I found similar are listed below this report. Attached backtrace is made with instructions from https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Procedure_gdb_and_debuginfod.

STEPS TO REPRODUCE
I'm not sure it can be easily reproduced. Most of the times the crash occurs on hovering over Panel with Task Manager or System Tray entries, but today it happened after minimizing an app. The other day it crashed when I was running a fullscreen program with Wine.

OBSERVED RESULT
plasmashell is automatically restarted after the crash but grouped tasks aren't displayed properly (missing "+" symbol) and some workspace elements seem to be otherwise broken (eg. KRunner logs "qt.qpa.wayland: eglSwapBuffers failed with 0x300d, surface: 0x57fbe8a2fcf0" to the journal).

EXPECTED RESULT
No crashes.
