Issues with SSAO in URP 12.1.2

When using Unity 2021.2.7 and URP 12.1.2 I'm getting some issues with the SSAO. If I enable Depth Normals, I get this blurry, swimming noise and banding away from the camera on all surfaces with normal maps. The banding seems to come from the mipmaps on the normalmaps, if I disable mipmaps the noise becomes uniform.
Example (I'm using an exaggerated SSAO to show the problem):


Here's the scene without SSAO enabled:


For comparison, here's the same material and SSAO settings in unity 2021.1.17 with URP 10.0
(Edit: Except this one had Downsample enabled, but that doesn't affect the problem.)



Bonus question:
If I set it to Depth only, that issue goes away, but then models appear faceted. This happens in URP 10 as well, is this a known limitation when not using Depth Normals?

 

In newer versions Unity also uses information from normal maps to calculate SSAO (and, well, it is the correct behavior).
Banding is probably due to lack of trilinear filtering on the texture.

 

Thanks! Trilinear fixed it. Using that and tweaking to sensible levels made it look pretty ok.
