Split screen Flash playback?

Every time I try and play a video from, say, Youtube, I get a split screen - horizontally - with a thick green line dividing the 2 halves.

The 'full' video can be seen in both halves.

This is extremely annoying but I have no idea how to rid myself of this affect.

Can any one tell how to fix this please?

Many thanks.

It just started with mine too. Very annoying. I read on a forum that it could be the video card going or over heating but mine is running at 41c but I kinda doubt that the card would be going cause I can game without a glitch. good Luck
