I've noticed my screen in a tiny bit skewed down to the right on my 17" MBP 2011 Anti Glare. No distortion or anything, just the actual rectangle that forms the screen image is not aligned with the physical screen. To make it clearer, the little black line between the image and the bezel is thicker on the top right corner and the opposite on the bottom. It's really small, but still noticeable and a bit annoying. The bezel and screen body are in perfect condition, nothing happened to it. What could this be?
