When moving a drawn shape over an animation: if the drawn shape has been scaled after being drawn, there are visual errors that occur when the layering puts the shape overtop of the animation resulting in the animation precluding the rendering of a shape overtop of an animation on the same or adjacent layer when the z-index (layering) puts the shape overtop of the animation. It is intermittent depending on the overlap, and may be due to the animation looking only at the original dimensions of the shape prior to scaling (unscaled shapes do not have this problem, only scaled up shapes - shapes that have been enlarged)
