Thank you for the bug report! If this is still happening on your system, we need a little more information.

Unfortunately the backtrace is incomplete and missing debug symbols for the following lines that we need to figure out exactly what's going wrong:

#5  0xb7df0f4a in ?? () from /usr/lib/libkonsoleprivate.so.1
#16 0xb7498cfe in ?? () from /usr/lib/libQt5Widgets.so.5
#33 0xb04ae961 in ?? () from /usr/lib/libQt5XcbQpa.so.5

Could you please install debug symbols and attach a new symbolicated backtrace generated by using `coredumpctl gdb` in a terminal window? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl for details about how to do this. Thanks again!

After recompiling/upgrading xwayland, mesa, libqt*, etc. the crash doesn't occur anymore - so I cannot reproduce it to create another stacktrace.
Comment 3 TraceyC 2024-08-28 16:09:21 UTC 
I'm glad to hear this is working properly on your system now. If the problem recurs, please open a new bug report for the current software versions on your system. Thanks!
