On iPad Pro 10.5'' (iOS 10.3.2), when the game launched via a URL rendering stops on the first frame. The game keeps running on the background; music plays, etc. but the frame remains frozen.

When issue is happening, there's abnormal order of events logged in the device console:

- applicationDidBecomeActive
- applicationWillResignActive
- applicationDidBecomeActive

i.e. main view may somehow lose focus and then get it back. In cases where the issue is not reproduced only one applicationDidBecomeActive event is logged, as it should.

Steps:
1. Download Xcode project from the Own Cloud ("zbs.zip") and open it
2. In Xcode, edit script so it would always "return true;"
3. Run on iPad Pro 10.5 2017
4. In device press: (wait...) > Ignore > (wait...) > Restart > (wait...)
5. Check Xcode console

Expected:
- applicationDidBecomeActive
[...]
- applicationWillResignActive

Actual:
- applicationDidBecomeActive
[...]
- applicationWillResignActive
[...]
- applicationDidBecomeActive

Test results:
iPad Pro 10.5 2017 | iOS10.3.3 | reproducible
iPad Air 2 | iOS9.2 | not reproducible

Important notes:
- Reproduced on both OpenGL ES 2 and Metal.
- No other (slower) device exhibit this issue.
- Setting breakpoints in Xcode prevents the issue from happening.
