Does anyone know how to sort this weird effect? The sides of the volume we're trying to render seem artificially hazy. I'm running it on 2014 MacBook Pro, Intel Iris 1536 MB GPU, Yosemite v 10.10.2 (14C1514). I've heard that this is only a problem on machines running OS X, and it doesn't appear on Windows machines.
I've also noticed it in some other places e.g. Leberba
khronos.org/bugzilla/show_bug.cgi?id=1337
Bug reported so closing
