How to reproduce: 1)Start plasma (wayland) session. 2)Switch from application launcher to application menu 3)Open the application menu 4)After a short time the plasma shell crashes (black screen) and restarts. I could reproduce it with following versions: qt-5.9.x kde-frameworks 3.35 and 5.36 plasma-5.10.x
it needs a complete backtrace with debug symbols to be useful
Created attachment 106584 [details] log of running plasmashell in gdb I've killed the plasmashell and started it from the debugger. The log contains two runs. In the first onethe shell terminated with: "The Wayland connection broke. Did the Wayland compositor die?" On the second run the QSGRenderThread SIGSEGV somewhere in mesa EGL code. It crashed while the application menu was open and the mouspointer above one of the categories.
Thanks for the follow-up
