I posted this in the applications forum and they said it's probably a hardware issue and I should return the machine. What do you guys think? Basically whenever I scroll in Firefox or Safari (both latest versions), the image looks something like this: Do you think this is a hardware issue? Also sometimes I'll click firefox in the dock and it won't even come up. I have to click is several times. Not sure if that's the same issue or something else. Should I just bring it in and show the Mac people at the genius bar? Any help is much appreciated. Thanks.
