Shadow artifacts are present when Directional Light is at a certain angle and with low Bias

--

-

How to reproduce:
1. Open the “Test Project.zip“ project
2. Open the “SampleScene“
3. Select the “Directional Light” in Hierarchy
4. Increase the Intensity to “1.5“ (to make the artifacts more visible) in Inspector
5. Observe the Game view

Expected result: The Cube GameObject’s shadow is uniform on one side
Actual result: The Cube GameObject’s shadow starts with an offset on one side

Reproducible in: 2021.3.40f1, 2022.3.38f1, 6000.0.10f1

Reproduced on: Windows 11 Pro (23H2)
Not reproduced on: No other environment tested

Notes:
- The scale of the artifacts changes on the size of the Game view (especially when it is in a 16:9 aspect ratio)
- Altering Directional Light Shadow attributes (under “Shadow Type”) will change the visibility and scale of the issue

    Actual! My asset pack ("Uniblocks" - https://assetstore.unity.com/packages/3d/props/uniblocks-hdrp-288750 ) is all about making buildings by seamlessly stacking many different blocks, and those shadow artifacts appears along each block in URP/BiRP, preventing me to releasing for those RPs. So far only Unity 6 preview HDRP is free from this issue...
