[iOS] Crash in UnityRepaint() when resuming the app with different landscape orientation if running at 60 FPS on iOS 10



When the orientation of the device is changed after the phone has been locked and before resuming the app, a crash occurs in UnityRepaint() if the app is running @ 60 FPS.

Steps to reproduce:
1) Open the attached project.
2) Build for iOS.
3) Run on a device.
4) Lock the screen.
5) Flip the device by 180 degrees.
6) Resume the app.

A crash occurs in UnityRepaint(); the view is rotated incorrectly and cropped. This does not occur if the 'Set 30 fps' button is pressed before locking the screen.

Note: the crash occurs in main() on Unity versions prior to 5.5.

Reproduced on:
5.6.0b2, 5.5.0p3, 5.4.4f1

    Any news regarding this crash?
    While we did wrap around this bug and at least reduced the reoccurrence of it greatly, we do get some UnityRepaint() crashes which might or might not have to do with this bug.
