I have been pounding my head into my keyboard over what could be causing this effect when Mac and Linux users (openGL) use DDS textures. I am pretty sure it has to do with the way I'm saving these textures, So what I have done is compiled multiple versions of the same textures in DDS format, each saved a little differently. What I need is a few testers on those OS's to try out each one of these texture packs and see if the above effect appears or not. (obviously we don't want it)
