its really annoying when you use it on a white background and scrolling isnt it? i feel ya
I've seen a lot of people put a microfiber cloth between the screen and keyboard when closed.
yea i bought something called "isaver2" on amazon and i make sure to use it at all times now. i am actually kinda paranoid about closing my macbook now cuz i dont want it to happen again. it was a horrible experience and especially visible when you were scrolling or on a white background.
