Hi, I have been running IOS 7 betas since the beginning on my Iphone 5. Ran the GM/Final since it came out. Parallax wallpaper/icons on desktop has been perfect. Yesterday I updated both my Wifes' and my iPhone 5 to iPhone 5S. I did a restore on both. On the iPhone 5S: I noticed that sometimes when in an app and pressing the home button to close, the background wallpaper kinda jumps/movies vertically and resets its position. It's as if it is not tracking the image position correctly when in an app and it resets the picture. It does not happen all the time but happens frequently. I tried to reproduce this on my iPhone 5 and cannot. This happens on both our phones so I can rule out hardware problem or weird glitch on my particular phone. Does anyone else notice this?
