SceneDepth Post Process doesn't work in 4.21 Android build

Hi, I have just noticed that SceneDepth node for post process material doesn’t work for Android build after migrating to 4.21. It does work on mobile previewer but not on my phone.

Post process material

4.20

4,21

I have attached the 4.20 project file [here][4].
It should be able to be reproduced just by simply changing the engine version.

I have noticed many of the post process input have been moved to Vulkan. I’ve made a Vulkan mobile build and it worked as intended, without any inverted viewport nor artifacts. But it introduced a lot of expensive overhead. I might have to look into the profiler for more detail. I’ll mark this as resolved for now.
