How to reproduce:
1. Download the project files "com.intel.vola-toolkit-master.zip" from the attached GitHub link
2. Open the project "VolaDemoHDRP"
3. Load the Scene "HDRPPostProcessingScene"
4. Enter Play Mode
5. Build the player (File > Build And Run)

Expected result: The built player and the Game view are identical in what they show
Actual result: The objects are properly drawn in the build but are missing from the Game view

Reproducible with: 2020.1.10f1 (8.2.0), 2020.2.0b7 (10.0.0-preview.30), 2021.1.0a2 (8.2.0)
Could not test with: 2018.4.28f1 (multiple warnings and missing references, due to the complicated nature of the project it'd take too long to attempt to set it up properly), 2019.4.13f1 (Console errors, missing references in Core RP Library 8.2.0)

Notes
- Reproduces both with HDRP (8.2.0, 10.0.0-preview.27) and URP (8.2.0, 10.0.0-preview.26), doesn't reproduce on the Built-In Render Pipeline
- URP and Built-In Render Pipeline project was tested on 2020.1.0f1 and 2020.2.0b7
- Unity Vola Plugins are being used
