"Grab RenderTexture" occurs when Main Camera "Clear Flags" is set to "Depth only" which adds extra GPU processing
How to reproduce:
1. Open attached project and open the SampleScene scene
2. Enter the Play Mode
3. Capture a frame in the Frame Debugger
4. Observe the "Grab RenderTexture" GPU marker, that seems to be useless and is expensive
Reproducible with: 2017.4.32f1, 2018.4.9f1, 2019.2.7f2, 2019.3.0b3, 2020.1.0a5
Actual results: resourceful "Grab RenderTexture" affects performance
Expected results: "Grab RenderTexture" should not occur
