I realize you don't have a Radeon but it sounds like you are having a similar problem. I imagine you screen shot is what they mean by an exploded polygon. I am not very GPU literate, so this is more a shot in the dark than anything. You can check the settings in you "Graphics Rules.sgr" to see what your setting are.
