Video flipped when app unpaused

Vuforia SDK Version: 7.5.20 - Description with steps to reproduce: When using ground plane in Unity and pausing and unpausing the app in portrait mode the background in some cases ends up upside down. Tested on an iPad Pro in Unity 2018.2.10 and Vuforia 7.5.20 iOS 12.0.1 Weirdly it's stable in upside down portrait mode and both landscape modes. - Development OS (Mac OS X, Windows, Linux): Mac OS X - Mobile OS and Version: iOS 12.0.1 - Mobile Device Manufacturer and Model name: Apple iPad Pro - Do the Vuforia Sample Applications show the same behavior?: Unknown

Even more weirdly if I set up a test with only 2 scenes, one non AR and one AR one that gets loaded in, which is how I have it in my actual app then that works ok. Grrr

Even worse even if my AR scene is unloaded if I pause and unpause and then reload the AR scene it comes in upside down.

 

I think I've found a fix for this. It's just to turn off 2 of the auto rotation modes, upside down portrait and landscape left.

Weirdly this not only stops the Vuforia background being upside down but the app still rotates into all positions.

A short lived fix :(

Unfortunately in order to support multi-tasking, which my app does it has to also support - or have turned on - all 4 orientations 

Stuck between a rock and a hard place

 

I've nailed the issue. If you turn off requires full screen then the issue presents itself even in the simplest test app I can make.

Unfortunately for me my app supports multi-tasking so I want that option off
