Created attachment 117676 [details] dmesg and coredump information (I'm not sure if Plasmashell is the correct category for this - please change it if needed.) When KDE desktop is used with Wayland, the desktop sometimes crashes completely and returns to the SDDM login screen. Most processes of the user are also terminated when this happens. This occurs randomly and not very often. The desktop may work for hours before it crashes. The crash may occur at any moment. I haven't noticed any specific actions that lead to crash. Please note that render loop is set to Basic in "kcmshell5 qtquicksettings" as suggested in the comments of bug #396614 Some dmesg and core dump information is attached. This time only drkonqi appeared in the core dumps. Sometimes other processes appear as well. System information: Arch Linux, x86-64, kernel version (uname -r): 4.20.3-arch1-1-ARCH Plasma package versions: 5.14.5-2 GPU: Nvidia GTX 980 Ti Driver: Nouveau KDE workspace themes: --Look and feel: Oxygen --Desktop theme: Oxygen --Cursor theme: Oxygen white --Splash screen: Breeze
Created attachment 117687 [details] Core dump information Another crash. Again only drkonqi appeared in core dumps.
> the desktop sometimes crashes completely and returns to the SDDM login screen. Kwin is crashing - which is what's bringing plasma and everything else down which is what we're seeing here in these crash reports. We need a crash dump of kwin.
