I can't tell if the update to iOS 7.0.4 caused this to happen or not, but essentially when you pinch to close in landscape orientation, the right side of the dock turns into a dark block/square chunk. Here's a link to the youtube video: http://www.youtube.com/watch?v=W68aH4afb18 Has anyone else experienced this issue? And if so, were you able to fix it? Also on the Apple support boards https://discussions.apple.com/message/23705369#23705369 If anyone is running the 7.1 beta, do you mind checking for this behavior? Thanks!
