SUMMARY
Sometimes when I wake up my two monitors from sleep, when I right click on the desktop to get the context menu, plasmashell crashes and then restarts.

STEPS TO REPRODUCE
1. Have two monitors (I have an AMD 6700XT video card)
2. Wake the screen from sleep
3. Right click on the desktop to get the context menu

OBSERVED RESULT
We should get the context menu without crashing plasmashell

EXPECTED RESULT
The context menu doesn't appear and plasmashell crashes.

Thank you for the bug report! Unfortunately I can't reproduce the crash myself on current git master, and the backtrace is incomplete and missing debug symbols for the following lines that we need to figure out exactly what's going wrong.

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!

I unfortunately, I couldn't access the gdb prompt in coredumpctl to type bt because I received the following error:

Cannot access "/var/lib/systemd/coredump/core.plasmashell.1000.24c367af4f044862be148099e8cbd88f.22882.1716552437000000.zst": No such file or directory

Comment 5 Nate Graham 2024-06-13 14:56:05 UTC

Darn. Unfortunately without that the backtrace is useless and unactionable. :( If this happens again, please feel free to open a new bug report, and make sure it has debug symbols. :) 

Your best bet is tro try using Arch's debuginfod server (see https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Arch_Linux) because from what I can tell, Manjaro doesn't have its own yet. This is probably also something to bring up with the Manjaro folks (see https://forum.manjaro.org/t/any-fix-to-find-debug-symbols-for-stable-packages/140688).

Comment 6 Ziad 2024-06-14 02:59:48 UTC

I posted a new bug report with a better explanation of the steps to reproduce and with a backtrace with debug symbols:
Bug 488474 (https://bugs.kde.org/show_bug.cgi?id=488474).
