    <thetext>Thank you for the bug report! Unfortunately the backtrace is incomplete and missing debug symbols for the following that we need to figure out exactly what&apos;s going wrong:

&gt; #9  0x00007fba6c7dfbc1 in ?? () from /usr/lib/x86_64-linux-gnu/qt5/qml/org/kde/plasma/core/libcorebindingsplugin.so

Could you please install debug symbols for Plasma, reproduce the crash, and attach a new symbolicated backtrace? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports

Hi Nate, thanks for the quick triage. Hope this has what&apos;s needed.

I&apos;m learning through additional context online that this is probably ungraceful handling of bad behavior in NVidia&apos;s binary graphics driver.
