I have seen a glitch like this on my 6 Plus, but I think it was with different icons overlaying weird on top of each other.
You can see what I'm talking about in the signal strength indicator of the secondary screenshot on the homepage of the Erodr app. Kinda funny that glitch has been on their site for months and I'm one of the only people to notice it. I'm your typical pixel-perfect designer, however. Link: http://www.erodr.com/v3/index.html
Thank you, this is exactly what I'm talking about. Glad someone else has this issue. Doing the landscape thing did temp fix it.I get that even without looking at images. Sometimes the status bar overlays my address bar in Safari. Running 8.1.3 and it has occurred in every version since iOS 8 came out (iPhone 6+). Usually if I rotate to landscape, then go back to portrait it corrects itself, but that never happened with iOS 7.
