gnome-shell 100% CPU usage
From time to time I see gnome-shell is using 100% CPU after I connect my laptop to a docking station (with 2 monitors). I am running GNOME under wayland and I guess this is wayland bug, so filing it here.
When I run strace on gnome-shell, I see tons of ioctls(DRM_IOCTL_I915_GEM_*)
on /dev/dri/card0
(see strace output: out).
I'm running Fedora 31 with latest updates on a ThinkPad T490s laptop
