Unicorn glitch??

A few weeks ago I had switched from my old phone (5c) to a new one with is an iPhone 6. And of course it updated itself to iOS 10 which I didnt want to happen but as I was playing the game, the unicorn gets more and more pixelated the longer you go. Im not sure whats causing this to happen but Id like that to have it fixed when you get the chance.
