Horizontal line artifacts when using Ambient Occlusion with Multi Scale Volumetric Obscurance
Reproduction steps:
1. Open the attached project ("1375337_22.1.zip")
2. Open SampleScene
3. Observe Scene and Game view
Expected result: There are no lines on the plane
Actual result: Horizontal line artifacts are visible on the plane
Reproducible with: 3.0.3 (2020.3.25f1), 3.1.1 (2021.2.6f1), 3.2.0 (2019.4.34f1, 2020.3.25f1, 2021.2.7f1, 2022.1.0b2)
Could not test: 3.1.0 (2020.3.25f1) (Ambient Occlusion doesn't work)
Notes:
1. The number and visibility of the lines in Game view depends on the Camera's FOV and clipping plane

The fix works, however it changes the rendering. AO is much "lighter" and "diffuse", if we keep the previous parameters.
Besides it seems that the edge detection has changed. I have light edges where they used to be dark.
Pushing the zBias back towards 0 works but brings back the banding
Adjusting the thickness modifier helps a little but the results are still different.
Increasing the intensity does not change the occlusion position.
All in all I'm not sure what to do with this....

I can verify that this is happening, and it looks quite bad with some combos of reasonable settings.

Hi, we are planning on launching our game next year, but this bug is still a blocker for us. So we are getting worried. The bug is causing prominent and distracting banding to appear in various environments and cutscenes in our game. This is not something we feel players will accept and it will directly affect our business as a studio.
It looks like it has been about a year or longer since this issue was reported. Has there been any progress on it?

This is also a blocker for us to ship our game.

This is one of the few issues that will affect my ability to ship my title.
