I'm pretty sure that those are a graphics system caching bug.  There is a cache 
of gradients to speed up blending with gamma. This feature stresses its limits 
because there is a lot more gradients to cache as we blend on top of blending.

Other things to add: monochrome bitmaps when antialias is off and error
