Since IOS7.1 has come out i now experience random jerky scrolling in things like safari, the app store, Mercury web browser. Even in settings as well. Its like a fast judder effect as you slowly scroll up and down, not good on the eyes. But then can vanish and come back again after some time. I just got an iPad 4 recently and the same day IOS7.1 came out so i upgraded this and all my other devices. I thought it was the iPad 4 but when i checked my iPad 3 which i have used non stop since day one i notice this also does it as well now, though it was not as bad as the iPad 4, which was a lot worse. So i done a fresh restore on the iPad 4 and set it up as a new device. It's a lot better now than it was but still does it. Anyone else experience this at all ?
