1) Open the 'TestScene' scene
2) Observe how the gray cubes are depth ordered in the game view of the editor
3) Go to Build settings and switch the target platform to Android
4) Enable VR mode with the Oculus SDK
5) Deploy to an android device
6) Observe the cubes are no longer depth ordered as before (the back gray cube renders over the middle gray cube) This is the bug

Notes:
- Disabling VR mode then deploying to the android device fixes the issue
- This issue does not occur in the editor
- This issue does not occur when deploying to standalone with VR enabled
