Here's a oh, so wonderfull paint illustration... http://bayimg.com/FaKLLaadj It's really hard to get proper photos of it, because it's not that bad, and when trying to get photos you actually need to make them bit blurry or the lines disappear into the moire noise.
Oh, crap, now I looked at you photo. No, that should not be happening to my knowledge. I'll take a look tomorrow on your example case on both displays we are shipping with (we had plenty of versions of the displays during the making on N9, some times to the better, some times to the worse)
