Thanks for reporting this issue to us! I'm trying to reproduce this problem in my side, with AMD Radeon HD 5870 graphics card, Win7x64 SP1 OS, 13.4 driver and Inventor 2013 SP2, but it could no be reproduced in my side. Do you have this card and run with problem? Does this relate with specific dataset?
The AMD cards we are currently using are 4870's and 7870's (about 6 total). Everything else from your test setup is the same. I think it might just be isolated to the parts that are using a chrome appearance.
