Nothing drawn after replacing clutter_actor_set_anchor_point with clutter_actor_set_pivot_point.
The main reason is position of graphicsLayer.
As I mentioned in bug109037, clutter has a different coordinate system from mac port's, so I think we don't need to recalulate the position after changing anchor position.
