Hi, I have a strange problem with my MacBook Pro 15’ screen since some weeks : White dots / pixels appears randomly on the screen, and slowly fade to finally disappear... It looks like dead pixels but the strange thing is that it disappears as it arrives. It happens randomly, whatever I am doing. I’ve tried to search for similar problems on the forums but found nothing. I tried to bring my MBP to the Apple Store but these dots weren’t visible at this moment. I’ve explained and show a picture of this problem to a Genius but he told me that he has never seen something like this... I have attached a picture of these strange dots. Any idea of the reason? Thank you by advance, Cheers.
