Application: plasmashell (5.27.1) Qt Version: 5.15.8 Frameworks Version: 5.103.0 Operating System: Linux 5.19.0-32-generic x86_64 Windowing System: Wayland Distribution: KDE neon 5.27 DrKonqi: 5.27.1 [KCrashBackend] -- Information about the crash: Switching between display setups with kscreen-doctor seems to crash plasmashell. It's not something that happens consistently though it always seems like on the second try of switching my displays back and forth I get greeted by my screens being completely black as plasmashell has crashed. Bear in mind I'm not switching between them rapidly but in 5 to 10 second intervals. Here's the command I use to switch to my big screen. kscreen-doctor output.DP-3.enable output.DP-3.primary output.DP-2.disable output.HDMI-A-1.disable And here's what I use to switch back to my main setup. kscreen-doctor output.DP-3.disable output.DP-2.enable output.DP-2.primary output.HDMI-A-1.enable The crash can be reproduced sometimes. -- Backtrace: Application: Plasma (plasmashell), signal:

Thank you for the bug report! Unfortunately I can't reproduce the crash myself on current git masyer, and the backtrace is incomplete and missing debug symbols for the following lines that we need to figure out exactly what's going wrong: > #18 0x00007f5e1471eada in () at /usr/lib/x86_64-linux-gnu/qt5/plugins/plasma/scriptengines/plasma_appletscript_declarative.so > #19 0x00007f5e1472c4ea in () at /usr/lib/x86_64-linux-gnu/qt5/plugins/plasma/scriptengines/plasma_appletscript_declarative.so Could you please install debug symbols, reproduce the crash, and attach a new symbolicated backtrace? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports Also, do you have any 3rd-party scripts or widgets installed? Thanks again!
