Error on iOS when gadget goes to sleep

I am building an application on AIR 22, and if an iphone goes to sleep, (after the time you set at display auto-lock), as soon as I reopen it and the app comes back, it loses half of the screen. The application is landscape aspectRatio and allows autoOrients.

After you do those actions half of the screen disappears, the rotation also is wrong and makes a completely weird rotation, (if you change the autoOrientation) .Another curious thing is that if you close the app and reopen it, you can rotate the phone and it starts working right again.

Does anybody had this issue? Can you reproduce it?
