--- Comment #4 from Jérôme L <jerome.4a4c+...@gmail.com> ---
kwin_wayland is "not present" in `coredumpctl list`
The following is `coredumpctl debug 9988` with kwin_x11 (version 6.1.4) on a
new user.
Worth mentioning: I have an AMD CPU (iGPU) and GPU.
Also I have an unusal installation (not out of the box) which could have
incompatibilities.
I will ask for help in a forum, thanks!
