In all of the applications I tried, including the one I'm developing, I've noticed that once I swipe from the left edge of the screen to go back to the previous one, I can sometimes no longer go to any other screen by tapping to any one of the buttons on the screen.
This certainly is a bug, which becomes more prominent once you try to go back a few times by swiping in the main interface controller and then tap on any one of the buttons on the interface that pushes another screen. It only pushes another screen once you swipe back again, and with a buggy animation. This is really weird. The only apps that do not have this problem seems to be Apple's own apps.
Is there any way to disable that gesture until this gets fixed?
