Created attachment 155229 [details] Plasmashell crash trace logs SUMMARY Plasmashell crashes when I use the close button in the Icons-Only Task Manager's window thumbnail tooltip. STEPS TO REPRODUCE 1. Launch two windows of the same application. I used Dolphin for my testing 2. Hover over the application icon in the task manager until the window thumbnail tooltip pops up 3. Close the second window using the X button OBSERVED RESULT Plasmashell crashes immediately after closing the window EXPECTED RESULT Plasmashell does not crash SOFTWARE/OS VERSIONS Arch Linux, Kernel 6.1.4 Nvidia 3090 w/ 525.78.01 drivers KDE Plasma Version: 5.26.5 KDE Frameworks Version: 5.101.0 Qt Version: 5.15.8 ADDITIONAL INFORMATION
Created attachment 155230 [details] Video of crash behavior
Forgot to mention that this is with Xorg 21.1.6
So this is 100% reproducible for me? I can't manage to make it happen. If it is for you, can you install or compile with debug symbols and then bet a backtrace from your stack trace? Then we can tell what exactly is happening. Thanks!
Created attachment 155252 [details] Backtrace with symbols Hi Nate, I used debuginfod to get the debug symbols. Here's the full trace.
Regarding reproducibility, today I noticed that I wasn't able to replicate the issue with Dolphin, but I've pretty consistently been able to reproduce the issue with Steam Windows. Can you try: 1. Launching Steam 2. Opening the Steam Friends list 3. Close the Steam Friends list using the window thumbnail tooltip close button
Thanks, that's very helpful.

Can't reproduce by closing my Steam friends list from the tooltip close button while the main window is also open, FWIW.
You're on X11, right? I'm on Wayland and I can't reproduce this. From the backtrace I suspect it's an X11-only crash. Can you try Wayland and see if there's no crash there for you?
Yes this is X11 only. I can not reproduce in Wayland.
