Steps to reproduce:
1. Open the attached project "ShadergraphQuestTest.zip"
2. Build it on a mobile device
3. Notice the Sphere in the Scene becomes red or brown without a hole in the middle

Expected results: The Sphere is Rendered Green with a hole in the middle
Actual results: The Sphere is Rendered brown or red without a hole in the middle

Affects GLES2/3. Works OK on Vulkan.

Reproducible with: 2019.3.0f2, 2020.1.0a16

Note: ShaderGraph brakes in 2019.2 and lower. Screenshots from StandAlone and from Android are in the description. The green SPhere is the StandAlone build and it is the expected results. IL2cpp makes the sphere be Rendered red more frequently while Mono makes brown more frequent color
