On my screen, when i'm in the internet browser. There seems to be an invisible line and whenever i'm in my browser whateber is below the invisible line is a duplicate copy of what is on my browser. So as I scroll down it looks like I'm scrolling down on 2 different screens! it's weird, it hasn't really affected my day to day it's just annoying. However somtimes if the screen is only one page and you can't scroll down, i can't see the bottom of the page because of the duplicate screen i have under the line.
