[HDRP] Black and white spots appear on the Sprites when the exposure value is above 8
How to reproduce:
1. Open user's attached "HDRP Flicker Test" project
2. Open the "SampleScene" Scene
3. Look at the "New Sprite" GameObject in the Scene view
Expected results: The "New Sprite" GameObject is a solid color
Actual results: The "New Sprite" GameObject has black and white spots
Reproducible with: 6.5.2, 10.0.0-preview.27 (2019.3.0a10, 2019.4.8f1, 2020.1.3f1, 2020.2.0a21)
Could not test with: 0.1.21, 5.16.1-preview (2018.4.26f1, 2019.3.0a12) because the exposure option was not added
Notes:
- Reproducible with Nvidia GPU, doesn't reproduce with AMD GPU
- Turning off the Skybox fixes the issue
- On High Definition RP version 6.9.2-preview and lower the exposure value required for the issue to appear is 15 or higher

Resolution Note:
The issue seems to be due to some imprecision when doing HW blending with a very bright background (your over exposed sky) and a not so bright foreground (the sprite) with sprite shaders.
At the moment the sprites shaders live outside of HDRP and not currently actively supported so this won't be fixed for now.
I would suggest the user to have the environment to not be so overly bright (if you fixed exposure is used, just set the intensity of the sky accordingly to the fixed exposure selected) and the issue should be less visible.
