SUMMARY Making the (new) appliction launcher show up (by pressing the Meta key) sometimes causes Plasmashell to crash on Wayland. STEPS TO REPRODUCE 1. Spam Meta (or your custom keyboard shortcut to toggle the application launcher) for some seconds to minutes, preferably shortly after login, when there are lots of jobs taking up system resources. -> Plasmashell will crash at some point (task bar disappears and returns shortly afterwards) 2. Repeat point 1 -> Plasmashell will crash again, but this time it won't come back on its own - open a terminal window and run the command `plasmashell --replace &` to get the taskbar back OBSERVED RESULT Plasmashell crashes sometimes when attempting to toggle the application launcher. EXPECTED RESULT Plasmashell shouldn't crash. SOFTWARE/OS VERSIONS Operating System: KDE neon 5.22 KDE Plasma Version: 5.22.1 KDE Frameworks Version: 5.83.0 Qt Version: 5.15.3 Kernel Version: 5.8.0-55-generic (64-bit) Graphics Platform: Wayland Processors: 4 × Intel® Core™ i5-3570K CPU @ 3.40GHz Memory: 7.2 GiB of RAM Graphics Processor: Mesa DRI Intel® HD Graphics 4000 ADDITIONAL INFORMATION /
This bug is around since I use Plasma Wayland, so it's not a regression.
Please attach a backtrace of the crash. https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl

Are you sure about the duplicate? This issue is Wayland-only, and it seems Bug 349519 is not...
It's a semi-random crash; the platform isn't super relevant here.
I have never experienced any such condition under Plasma X11, so I think this might deserve further investigation. At least 95% of my Plasma Wayland crashes are caused by this issue. I wonder whether other users can confirm this behaviour.
Also, the fact that the issue is easier to trigger when system workload is high sounds suspicious to me. Possibly a race condition?
