I'm not sure if this has been seen yet, since I have only gone through the last few pages of the bugs to see if this is one of them. I noticed from 12-9-2008 that you said you wanted to get something public out there I wanted to make sure you have seen this issue. It's happened to me twice before and this is the first time I managed a screen shot.
I think that this is occuring after the box has gone in and out of hibernation a few times. I have attached the screen shot. Everthing on the screen looks like geometric drawings, from the fish to the landscape. You'll have to see the scren shot to really understand what I'm talking about. This is happening on a brand new HP box and monitor. Here are the stats:
AMD Phenom 9750 Quad Core at 2.4 GHz.
8 Gigs of RAM
Vista Home Premium 64 bit
Running an ATI Radeon HD 3650 card.
Let me know if you need anything else from me.
Thanks,
T Bryan
