Hi everyone. I've recently been noticing an issue with the screen on my rMPB. I'm hesitant to take it in since this one does not exhibit burn-in, and the first one I got did. I think the issue is that the backlighting is uneven, but I'm not so sure. It is not uneven enough to be noticeable on a black background, but when I move a solid white or gray window around, I can see non-moving light and dark areas above the image. It's also noticeable on light colored backgrounds. I tried taking a video of the problem: http://www.youtube.com/watch?v=dGZIVUYS_cY Has anyone else noticed this?
