Greetings! My 2.2 ghz MacBook has been giving me some 3d video problems. Here's a snapshot of the issue: At first I only noticed this issue when I was playing a 3d game, like World of Warcraft, but now as you can see it is cropping up in random parts of Leopard's 3d items. Notice the weird splotches around the icons for Mail, iTunes, and the Trash Bin. I'm not quite sure where to begin troubleshooting this problem. I'm fairly certain that there isn't a hardware issue going on as these issues never manifest when I'm booted into Windows XP via Bootcamp (I sometimes play World of Warcraft and Civilization IV on the Windows side). Other than that I've tried reinstalling 10.5.4 with the combo update as well as reinstalling any 3D games.
