Summary: kwin_wayland crashes when connecting external screen
Classification: Plasma
Product: kwin
Version: 5.26.0

SUMMARY
When plugging in an external screen to the HDMI connector, kwin crashes or
freezes about half the time, taking down the entire session. This HDMI
connector is attached to the NVidia dGPU in my laptop; I am using the
open-source nouveau drivers for that one.
systemd-coredump shows a stacktrace in the logs but I am not sure how to get
symbols for that one:
