+Subject: [PATCH] clutter: Trigger repick on animation-less transform changes
+
+We have a mechanism to trigger repick after animations on
+clutter_actor_set_final_state(), but this will not happen if
+animations are disabled.
+
+In this case, shell transitions and other typically animatable
+changes on the transform of actors will not naturally trigger
+a pointer repick when those get instantly changed to the final
+state, possibly preserving the cached state and missing the
+just popped in actor altogether.
+
+Trigger an instant repick on animation-less transform changes,
+so that these situations are also handled correctly, and the
+pointer drops the cached state and is able to find the new
+actor.
+
