I have a white MacBook and today in Safari when I was scrolling down web pages they started to slowly turn black and white and eventually fade away. (As shown) I'm not exactly sure why this happened, and when I quit that session of Safari it didn't do it anymore. The only reason that I'm worried is because my 1 year warranty runs out in 3 days... I don't want it to start acting up after my warranty is up. Do you think this was a one time thing or it may start to do it again in the future when I don't have a warranty anymore?
