Please help me out. I have a MacBook Pro and I have had a graphics issue that has been intermittent but steady over the past at least six months. The screenshots make everything clear - when scrolling down I get inverted and different colors in the screen. The last four images are a progression as I scroll down and up. It isn't limited to any specific applications. http://imgur.com/YznSI.png[/ITMG] [img]http://imgur.com/Pa9Ya.png I have plenty more screenshots if you want to see them. I did an OS reinstall as recommended by the Apple Store Genius and it didn't work. If there is a fix for this or if you can help me understand what is happening, I would love to hear it. Thanks so much! I am more than happy to answer any and all questions.
