Created attachment 155069 [details] crashlog SUMMARY I'm getting frequent, seemingly random crashes on KDE Wayland. Most of the times it happens when opening a new program, but sometimes it happens just by merely using Firefox. I use the Overview Desktop Effect to open my apps, but this crash was also happening with the Applications Menu widget. Not sure if both types of crashes are related, but in one of the cases my panels just disappear and restart automatically a few seconds later, while in the other one the entire session crashes and restarts, killing off all of my open processes. There doesn't seem to be a specific way to reproduce the issue, but I was able to reproduce the crash and get a crash log by opening BitWarden and then, immediately after, opening Authy. STEPS TO REPRODUCE 1. Open a new program OBSERVED RESULT Sometimes plasmashell will restart itself, other times the entire session will crash and restart EXPECTED RESULT Program opens and session remains intact SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch Linux/KDE Wayland (available in About System) KDE Plasma Version: 5.26.5 KDE Frameworks Version: 5.101.0 Qt Version: 5.15.7

UPDATE: This actually seems entirely related to the Overview Desktop Effect. I was under the impression that I saw this behavior with Application Launcher, but while I am able to reliably replicate this crash in Overview by opening BitWarden and Authy in quick succession, I am unable to replicate with Application Launcher.

I moved to krunner, but it's equally plausible that kwin is deleting a runner whilst a thread is active.

Either way, this could actually be a symptom of the same issue. I'll wait for Plasma 5.27 and check if it still happens after that commit.
Actually, the version of krunner I am running does include that commit, so it seems like this issue was not fully resolved.
