Reproduction steps:
1. Open the attached “test project (2).zip” project
2. Open the “Outdoors” Scene
3. Observe the Game view

Expected result: The red sphere mesh is visible
Actual result: The red sphere mesh is not visible

Reproducible with: 6000.0.0b12, 6000.0.21f1
Not reproducible with: 2021.3.44f1, 2022.3.48f1, 6000.0.0b11

Reproduced on: Windows 10 (User reported), Windows 11
Not reproducible on: No other environment tested

Notes:
- Reproduces when Injection Point is set to “Before Rendering” or “Before Transparent” in the ‘RenderFromCameraCustomPassVolume’ GameObject
- Enabling the Frame Debugger makes the red mesh reappear
- Customer reported that the method also breaks upscaling effects such as DLSS and FSR as enabling them causes the Custom Stencil pass to flicker
