Hi, Just received my MBP 2nd replacement and I am facing the same issue AGAIN... Basically when scrolling up or down in Safari or Mail some horizontals lines appear, like static pixels. It's difficult to explain really but very annoying... Anyone else have the same issue? I dunno whether I should return it again..hassle as I have to wait 3 weeks again (Made to Order, French Keyboard, etc...) or maybe a software update will fix the issue? I will try to record a video and post in youtube to let you see.
