There appears to be some sort of “off by one” error happening when you have a non 8 bit image that is composited on (Over/Atop/etc) a image sequence.

Check out /img/img1/over1 at frame 8.

Its a Color COP composited over a Image Sequence that ended the previous frame.

If the color cop is set to 8-bit integer then you get a 0 alpha (good), but if you set it to 32bit you get an alpha (bad).
