Does anyone have a 2.8 or any new MBP that is having redraw problems? When I drag windows around, I get a doubled horizontal line on the edge of the windows. Also during Quicktime playback a get a horizontal line doubling running across the whole image that comes up about every 8-10 seconds and make the video slightly wave. When I output video to my HDTV using displayport to a DVI/HDMI adapter the video on the HDTV looks fine - no doubling line issues, same for the window redraw. The redraw only happens on the MBP screen and happens under either one of the 2 graphics cards. Anyone have this problem or know what's happening?
