If not, I would recommend that use something like sprite.opaqueBackground = 0xFF0000; or perhaps you could use sprite.graphics.beginFill (0xFF0000); sprite.graphics.drawRect (0, 0, 100, 100);
Both of these would preserve a solid background color for an object, and would be retained between frames (and would be compatible on non-GL targets)
Yeah, I believe that is occurring as a part of the OpenFL renderer at the moment. In order to have full control over the commands used, you would be looking at Lime, or something else lower level. Otherwise, you should be able to set the color and clear each frame, I don’t know that it would be very expensive
