I just got a new late 2011 15" anti-glare MBP. When scrolling on web pages the text flickers and gets a little blurry. It's enough to be noticeable and annoying. I did some research and this issue seems to be called pixel walk. Went to this website http://www.lagom.nl/lcd-test/inversion.php and my screen flickers a lot - all boxes when scrolling and 4a or 2b & 4b depending on where they're located on the screen. I have a Lenovo laptop right next to it that has absolutely no pixel walk (or at least not enough to be noticeable). The Lenovo's resolution is lower (1368x768) than MBP and screen is glossy. I was wondering if any MBP's don't have pixel walk issues? Is there a difference between glossy and ant-glare in regards to pixel walk?
