I reported it a couple weeks ago. It's a major issue with my game, where everything is animating over a background and leaving garbage.
I sure hope Makslane can get it stomped soon. Whenever a sprite is drawn it leaves a trail of background colored garbage off the lower right corner of the sprite, even on top of actors that are layered above the sprite.
Doesn't do it on pc exports, but all sprites do it on the gp2x.
