Anyone else having this problem? I just noticed it today. It started with what looked like underscores beside the app name on 2-3 apps. Something like this: "Yelp_" and "_Photos" They were both in folders. Then, later today, I noticed that the lines appeared all across the screen horizontally, maybe 10 of them of differing widths. It lasted for a couple of seconds, until I pressed the home button. Then went away and didn't come back. Sorry I couldn't capture a screenshot in time. I will try next time. The best I can do is find something similar: It's like the line above, very thin (looks like a thin underscore) and disappears after a button is pressed. They were different widths and there were many of them.
