I was watching some YouTube videos and when I changed the volume up/down I got this distinct grayish bar of uneven light across the screen. Obviously it’s something I need to take to an Apple store but I wanted to know who else has had this. I need to make the issue more clear... I know what the volume on YouTube looks like. This is a distinct grey bar that shows up across the screen. I adjusted the brightness of my original screen shot to show you what is going on.
