Scroll animation glitches when using black background

Ordinarily, the scroll on background scroll works fine. However, when the background is solid black, the scrolling object glitches when it approaches the edge of the screen.

To reproduce: create a simple object (shape, etc), set the animation to react on bg scroll.

If the background is black (#FF000000), the object glitches. If the background color is anything else, including #FF000001, it works fine.
