I'm using Unity 6 (URP) and I'm seeing dark jagged/shadow-like artifacts on my ground mesh.
What I've tried
Disabled my Directional Light ("Morning Sun")
Disabled my Global Volume
Removed the Terrain completely
The artifacts are still visible
The artifacts are visible in both the Scene View and Game View
Additional observations
Since the artifacts remain when the Directional Light is disabled, I don't think they are actual shadows.
They appear as dark patches or jagged lines on the ground.
I can also see a diagonal line across the scene.
The issue remains even after removing the Terrain object.
Environment
Unity 6
URP (Universal Render Pipeline)
Windows

Question
What could cause dark shadow-like artifacts to remain visible in Scene View even after disabling the Directional Light and Global Volume?
Are there any Unity 6 / URP debug views, rendering settings, decals, baked lighting, z-fighting issues, or material settings that could produce this effect?
Any suggestions on how to diagnose the source of these artifacts would be appreciated.
