The vfunc was not tied to "paint", but was used by MetaWindowActorX11 as part of the "update" mechanisms. In order to make that more clear, special case it in MetaWindowActorX11 by type checking the surface actor, handling the case without MetaSurfacActor abstraction. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1285
