Created attachment 118203 [details] dmesg and core dump information Sometimes when using KDE desktop with Wayland, the desktop crashes completely. This occurs randomly. The system typically returns to the SDDM login screen. Bug #403653 is related. Crash information of KWin was requested. A file is attached, containing some information from dmesg and coredumpctl. For some reason the core dump is truncated. I'll try to provide a complete one later. No other core dumps were created when this crash occurred. System information: Arch Linux, x86-64, kernel version: 4.20.8-arch1-1-ARCH KWin package version: 5.15.0-1 GPU: Nvidia GTX 980 Ti Driver: Nouveau KDE workspace themes: --Look and feel: Oxygen --Desktop theme: Oxygen --Cursor theme: Oxygen white --Splash screen: Breeze Please note that render loop is set to Basic in "kcmshell5 qtquicksettings" as suggested in the comments of bug #396614
Please keep in mind that you have to repackage kwin and kwayland because on Arch Linux there is no such thing as debug packages.
Please note that nouveau is quite often crashing on X11. Given that I consider it unlikely to work on Wayland.

The crash is still lacking debug symbols.

So are these crash reports completely useless without debugging symbols? I can try to install symbols next but it seems to be a bit complicated.
