How to reproduce:
1. Open the user's attached "URPDecalMipMapBug.zip" project
2. Open the Scene "SampleScene"
3. Observe the edges of the red cube in the Game View
Expected results: There are no white/light gray pixels around the cube
Actual results: There are white/light gray pixels around the cube
Reproducible with: 12.0.0 (2021.2.0b15), 12.1.4 (2021.2.10f1), 13.1.5 (2022.1.0b6), 14.0.0 (2022.2.0a3)
Could not test with: 7.7.1 (2019.4.36f1), 11.0.0 (2020.3.27f1) because Decal was not yet introduced in the Shader Graph
Note:
- The issue is reproducible in HDRP and URP
