I think I have similar issue with Unigine Heaven 3.0 :

A webgl demo that has the issue too is at http://www.findyourwaytooz.com/
It appeared with Kernel 3.8 too. Kernel 3.7.9 did have this.
With a previous Mesa there was the same kind of issue with Lightmark, but with latest mesa it is gone ; maybe the remaining corruption is related to compressed textures ?
Your screenshots are very similar to what I see with other Unigine's demos. Your webgl demo also seems to exhibit the same corruption issue. I would say you are right about some specific kind of textures not being correctly rendered, while others are. What kind exactly is to be determined.
