I'm experiencing this crash roughly every 20-30 minutes. It has happened ever since updating to KDE6. As part of the upgrade, I was forced to update to nvidia-drivers-560.35.03-r1 because the 550 drivers presented with huge graphical glitching and flickering. It occurs on both the Xorg and the Wayland backend. SIGSEGV [Current thread is 1 (Thread 0x7fb664a2ea00 (LWP 50946))] (gdb) bt #0 0x00007fb66a0d38ec in ???

Clarification: "because the 550 drivers presented with huge graphical glitching and flickering *on the wayland backend only*".
Thank you for the bug report! I'm not able to reproduce this on git-master. 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 0x00007fb66a8deb05 in ??? () at /usr/lib64/libQt6Core.so.6 #26 0x00007fb660315b80 in ??? () at /usr/lib64/libPlasma5Support.so.6 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!
