At specific angles in the Game View, shadows appear segmented when using a 'physical' camera setup.

Steps to reproduce:
1. Open the attached repro project
2. Open the 'Test' scene
3. Set up your Editor layout in a similar way as in the provided screenshots
4. Notice the segmented shadows, as well as the difference between Game and Scene views

Notes
- This bug only reproduces under certain angles in the scene view. Have not been able to reproduce it in a build (yet).
- Make sure you have the AR set to Free Aspect
- You may have to move the camera a bit to get the bug to reproduce
