I just got myself the brand new and maxed out MacBook Air 13" 2012. And damn this machine is a beast But I have just noticed that when I scroll the text and vertical lines on the screen tend to flicker a little and it is driving me crazy. Is this normal? If you do a google search and you try scrolling the vertical line just above the search results flicker when you scroll (try scrolling slowly) Also the text flickers a little. In Facebook you can see it on the comment/like part underneath a status (the icons). Do you guys experience this? Or do I need to take it back??
