If you open FrameDebugger and look at the FullScreenPassRendererFeature, _{}BlitScaleBias{} is 0,0,0,0.

Steps:

1. Download and open attached project (URP_FullscreenShader-1.zip)
2. Make sure SceneView is not opened
3. Open SampleScene, observe GameView

See attached videos for repro.

Actual:

• GameView shows all white.
• In 2022.2.10f1, if you open SceneView and go back to GameView, the rendering is correct.
• In 2022.2.19f1, if you open SceneView, nothing happens, both SceneView and GameView still white

Expected:

• Without opening SceneView, GameView shows inverted skybox color with a cube

Reproducible:
2022.2.19f1 (still white even opening SceneView)
2022.2.10f1 (start to render correctly if opening SceneView)
