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

iOS

Dec 18, 2016

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

Did not reproduce:
5.2.4f1

Devices:
iPhone 7 iOS 10.2 - repro
iPhone 6 iOS 10.0.2 - repro
iPhone 7 iOS 10.0.2 - no repro
iPhone 5S iOS 9.1 - no repro

We're seem to have related problem even in 5.5.2f1. Here is the stack:

A problem appears when we're trying to perform a social network authorization and opening a Safari for that. Prior to Safari completely loads the form, the focus returns to the game and the crash occurs.

I am having the same issue, and looks like this is a duplicate of https://issuetracker.unity3d.com/issues/ios-changing-the-screen-orientation-via-a-script-sometimes-results-in-corrupted-view-on-ios-10
