[Android] [URP] Shader rendering differs on Mali, Adreno 5XX-6XX, Adreno 3XX GPUs

Package: Scriptable Render Pipeline Universal

-

How to reproduce:
1. Open the attached project
2. Build & Run project on Android
3. Compare rendering between devices

Expected results: All devices render the scene the same
Actual results: The shader rendering differs on Mali, Adreno 5XX-6XX, Adreno 3XX GPUs

Reproducible with: 2020.1.0b13, 2020.2.0a15 (LWRP 8.1.0)

Notes:
- Same results with Vulkan and GLES3

  1. Resolution Note:

    This is expected as a function that generates random number for the noise (which is later applied to the texture in the project) uses large numbers. Depending on GPU those numbers are losing precision hence the different results between GPUs.
