I've noticed recently that when I put my computer to sleep; and then come back later to start it up, there is a light red 'streak' for lack of a better word in the area where the login box pops up. After it does pop up - the streak is gone though, and I haven't noticed it in any other situations, even when the screen is entirely white or black and it should be easy to see (if it were permanent damage to the screen). I'm not very close to an Applestore, and probably won't have the chance to go to one for a few months. Anyone else had a problem like this?
