Hi, Just bought my brand new MBP 17 i7 with Antiglare and so far loving it except for the same issue I had with my older mid 2009 17 incher. This is the issue; When loading up processor/GPU intensive applications and when the fans actually do kick in, there will be 2 distinct 'aura' marks above where the fans are located (Left and Middle) on the LCD. This aura marks seems/looks to be backlight leakage/uneven backlight proportional to the amount of heat/volume of air the fans are exhausting. This phenomenon has been documented in the past and I guess Apple can't seem to get it right. Thinking this could be a one off lemon in the 2010 line, i went to the Apple store and got it replaced and guess what, the same issue. Would like to post this for anyone that has noticed this issue and say you are not alone on this one It will continue to be there until they find a way of expelling the hot air from the sides and not onto the LCD. Kudos Apple!
