Calling clutter_actor_get_allocation_box() can potentially cause a re-layout, which in _st_create_shadow_pipeline_from_actor() would mean invalidating the shadow_spec passed as a parameter, which could crash the shell later on since the value for shadow_spec->blur passed from _st_create_shadow_pipeline() to blur_pixels() would not be a valid one. Thus, whether the ClutterActor has an allocation before calling clutter_actor_get_allocation_box(), and early return if needed. https://gitlab.gnome.org/GNOME/gnome-shell/issues/36 Closes: #36
