Når nørder keder sig

Following the iMac EFI 1.2 update, I’ve run into an extremely annoying screen problem; When I move my mouse from the bottom half of the screen, past the middle, to the top half, a few lines of pixels duplicate themselves.
Look at the bottom of the letters in the line just above the blue bar. It’s more obvious in the u and a letters of “Virtual Arrays”.
Sorry about the quality of the images, they were shot with my mobile phone.

The same thing happens vertically when I move my mouse from the left to the right part of the screen.
Anyone got any ideas?
