How can I stop my computer from flashing white on my screen when I scroll or watch...

...videos? When I watch videos and scroll, random rectangular shapes just flash white on the screen. I also can't record stuff on the screen, which sucks too. This is on a Mac.

You have to update the video drivers. That is what I've always done when I reformat and have that problem.
