Lines small little lines

[prizner]

So I just had an issue pop up recently when playing most games and if I alt tab out of the game I can see it on the desktop too I get theses small horizontal lines that run across my screen. The lines are not obstructing my view, it's more like the screen is made of water and its rippling a bit. Even with vsync enabled

Currently running 2 gtx 460's in sli

Is it a Moiré effect from the resolution of your screen to the reduced resolution of the game?
