So I finally got round to getting a 15" MBP with anti-glare display, however there is one issue that is really irritating. Basically, anything that moves on the screen has this weird grain/grid over it. It also seems like the backlight is flickering a bit which might be related to grain on a moving image. This only happens with moving images. Good example is if I move an icon - looks fine on its own, soon as I move it, the grainy grid appears over it. Not a big deal for an icon, but imagine playing a movie and having that all over it, because that is exactly what happens. Anything that moves - whether it be an icon, video, scrolling in Finder, a grainy effect appears over it. What should I do...? Anything software related that could be causing this? Or is it a bad display? I've reinstalled OS X, reset PRAM etc..
