I have then new Santa Rosa 2.2ghz Macbook pro. I think I have an issue, but I'm not sure what to make of it. When running any type of game, even really less demanding ones, I get creases occassionally in the screen that look like this http://www.videohelp.com/forum/archive/horizontal-lines-on-video-playback-with-vista-t330614.html It's kind of like horizontal lines shifting and distorting the image. Is this a problem with the graphics card or the macbook pro? Is it driver related? Has anyone else experienced this? any help would be greatly appreciated!
