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




Priority: 2Necessary for shipping a final release


Severity: 1Crash or major loss of functionality

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.

1) Open the attached project.
2) Build for iOS.
3) Run on a device.

    Does it happen even when the game is not running at @60 FPS?

    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.
