When this bug was first reported in 17.10 it was a Wayland-only bug and the fix for that is awaiting review: https://gitlab.gnome.org/GNOME/mutter/merge_requests/171
However since 18.04, a patch was introduced to Ubuntu/Debian that seems to be affecting Xorg sessions now too. So I think that also needs removing to fix this bug: clutter-Smooth-out-master-clock-to-smooth-visuals.patch
