I'm noticing a very subtle mesh or lattice patter forming on my screen when viewing a video or even dragging icons or scrolling a screen. It happens for instance, when move my mouse around the dock and the icons magnify. They get this pattern over them...very hard to see, but it's there. (13" MBP BTW) I don't recall seeing it on my previous 13" aluminum. Anyone know what it is? Is it just the dot matrix pattern inherent in the screen? I have no other issues with the screen. And this isn't even really an issue, just more of an annoyance. Thanks.
