Description slavomirr 2021-11-12 13:46:48 UTC
Application: kwin_x11 (5.23.2)

Qt Version: 5.15.2
Frameworks Version: 5.87.0
Operating System: Linux 5.14.14-1-default x86_64
Windowing System: X11
Distribution: "openSUSE Tumbleweed"
DrKonqi: 5.23.2 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:

Added a virtualized hardware component to a VM from within Virt-Manager GUI. Any component that requeires the VM to restart after being added to the VM template makes KWin crash and restart. Even if the VM is powered off. Example: RNG device /dev/urandom
Aadding components that do not require the VM to be restarted will not make KWin crash.  Example: virtual network interface

The crash can be reproduced every time.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
