I've come across this issue where graphic artifacts are rendered when working with a part model and an assembly.  I get the following screenshot with what looks like a "crystaline" structure when I rotate the part:

I can click to the other screen and the actual part re-appears.  So to fill in some details.  I'm using Solidworks 10 SP 4 with Nvidia Quadro 3800 video card.  I think i have a fix for this but wanted to see if others have this problem and have already solved it....

Anyone?
