[iOS] [Metal] Depth-Only Camera blacks out screen when anti-aliasing is enabled



To reproduce:
1. Open attached project
2. Open "TestScene" scene
3. Play the scene
4. Press the Toggle Depth Camera button
5. Notice that red sphere overlayed the scene
6. Deploy to iOS device (iPhone 6 plus)
7. Press the Toggle Depth Camera button

Actual behavior: you will see the red sphere with a black background (not the same view as in step 5)

This is fixed for iOS versions 10 and above and will *not* be fixed for older versions due to risk of introducing other regressions.
If this issue is blocking anyone from shipping a game, the best workaround is to conditionally disable MSAA for older iOS devices.

    I initially posted a comment under this issue:, which is very similar. I'd like to re-post it here. Note that the developer mentioned it had been fixed for iOS10 and later. I reproduced it with iOS12.

    I think this issue is only partially fixed. We recently ran into something very similar using Unity 2017.4.22. My test device has iOS 12.3. In our case, the repro conditions are following:

    * iOS build running on device (does not repro on other platforms, or in the editor)
    * Multiple cameras in the scene with various depths; preferrably with lowest depth camera drawing skybox only, other ones clearing depth buffer and drawing some 3d objects
    * Add a directional light to cast shadow
    * Set up 3d objects to cast and receive shadows
    * In quality settings, delete all levels except one, enable both MSAA and shadow (any quality)

    The symptom is that only the camera with highest depth is rendered.

    This is NOT fixed in 2019.1.2
    Is there any workaround?

    We are seeing the issue on iPad Air 2 (A1566) and iPad mini 3 (A1599) devices.
    Other iOS devices tested do not have the problem (A1459, A1954, A1778)
    App built on Unity 2014.4.3
