[iOS][Metal] Shadows on UI camera cause Main Camera to not render the image

Graphics - General

-

Steps to reproduce:
1. Open the attached project ("884781 repro.zip")
2. Enter play mode
3. Notice that there's a skybox, two cubes and two capsules in the scene. (One capsule is having its "Cast Shadows" field toggled every second)
4. Build to iOS
5. Notice that only capsules are rendered when "Cast shadows" is on.

Expected: Scene fully renders regardless whether UI objects cast a shadow or not

Reproduced on: 5.5.1p4, 5.6.0b9
Reproduced with: iPad Mini 4 (iOS 9.3.2)
Could not reproduce on: 5.4.4p4 (unable to downgrade), OpenGLES2 API (no repro)

  1. Resolution Note:

    A7/A8 SoC devices cannot resolve AA and store at the same time. Hence after resolving (on switching RT) we cannot render to it anymore. The workaround would be to disable AA on pre-A9 devices, also for performance reasons.
