[URP] Shadows are jagged when Shadow Atlas Resolution is set to 4096



Steps to reproduce:
1. Open the user’s attached project
2. Open Assets/Scenes/IvyTable.unity
3. Open the Game view
4. Select Assets/Settings/UniversalRP-HighQuality.asset
5. In the Inspector window set Shadow Atlas Resolution to 4096
6. Observe the Game view

Expected result: Displayed shadows aren’t jagged
Actual result: Displayed shadows are jagged

Reproducible with: 12.1.7 (2021.3.7f1), 13.1.8 (2022.1.9f1), 14.0.3 (2022.2.0b1), 15.0.0 (2023.1.0a3)
Couldn’t test with: 10.9.0 (2020.3.37f1) (Shadow Atlas Resolution setting doesn’t exist)

Reproducible on: Windows 10

  1. Resolution Note (fix version 2023.1.0a12):

    Fixed wrong shadowmap size used in soft shadows. It now uses the actual shadowmap size instead of the requested size. This fixes incorrect shadow filtering with atlases that are larger than required to fit all lights.

    However, shadows are still resolution dependent. A high resolution shadow map will get downgraded to a lower resolution when the atlas does not have enough space.

    The filtering is still done in pixels instead of area. This means lower resolution shadows will be blurrier and softer than high resolution shadows.
    This is by design.
