    Whenver I minimize an application I get a checkered pattern until it's minimized on the dock. I also get this checkered pattern when I go into full screen in powerpoint.

    Any idea what could be causing this?

    I already ran disk utility and repaired.

    Is your machine an A1150, A1211, A1212, or A1151 model? Check the bottom.
