Reproduction steps:
1. Open the attached “texelsize-repro.zip“ project
2. Open the “Assets/Scenes/SampleScene.unity“ Scene
3. Observe the Game View

Expected result: Black borders are seen around the white cubes
Actual result: The entire game view is white due to the absence of cubes' borders

Reproducible with: 2022.3.49f1, 2022.3.51f1, 6000.0.22f1, 6000.0.24f1
Not reproducible with: 2022.3.48f1, 6000.0.21f1
Couldn’t test with: 2021.3.45f1 (errors)

Reproducible on: M1 Max MacOS 14.6.1
Not reproducible on: No other environment tested

Notes:
- Outline (Edge Detection) pass that uses the Hidden/Outlines/Edge Detection/Outline shader in a blit: here if you check the _BlitTexture_TexelSize under the vectors section in the frame debugger, the values are all 0
