After updating to 10.8, I noticed some light blue dots on the top of the screen. I thought it could be either a stuck or a dead pixel, but the blue dots are only visible when the top menu bar is showing. They don't appear when using programs in full screen mode or watching movies. I have attached a screenshot where you can see the problem. You can see two right of "Vis" and two around the battery symbol. Have anyone seen this before?
