I haven't been able to recreate this in anything but the app store, but I notice when I scroll in the app store, sometimes the page will be very jittery, almost as if the screen is switching between parts of my finger. I so far haven't been able to recreate this anywhere else, so I am assuming this is an iOS7 glitch? I think it happens when my finger scrolls the page while grabbing between two app listings, along the grey line. Anyone notice this?
