So I just got a new Macbook Air and after a couple minutes of playing around with it I started to notice these really thin gray lines running along the dock area. They seem to fade out the higher you go on the screen. They are further apart than a pixel so isnt just some natural screen door effect. They are even noticeable from a few feet away. Is this common issue or are the geniuses gonna look at me like Im crazy when I take it in later this week? Has anyone else noticed this on theirs? Very disappointed. Thanks in advance.
