Jitter/Pixel Noise artefact

[kim05]

Visual glitch I do not know how to name properly, but very annoying. Started showing up out of nowhere. Please, watch the videos to understand what I mean.

So far I've tried removing Lights, CUA Lights, CUA Reflection Probes, tuning Skin Materials, Scene Lighting settings. All to no effect.
On video 2 you can observe how removing the skybox "fixes" the problem. However, I would like to find a real fix for this without disabling the skybox as this way ruins my idea for a scene. This is definitely not a problem with CUA as the same result can be achieved with the default VAM start up scene:

Basically it seems if I put a white or reasonably close to white background behind Person the pixel jitter will begin to show.
I understand it's a weird and specific graphics glitch, but my hope is that someone had seen something like that happen and has a clue as to what might be causing it.

My specs:

Video Card - NVIDIA GeForce RTX 3060 Ti (Nvidia Driver up to date as of posting this thread)

Processor - Intel(R) Core(TM) i9-10900F CPU @ 2.80GHz

Ram - 64 GB

Please, share your thoughts and ideas as I've ran out of those for now.

Having this same problem currently. It seems to be when there is no light data on the skin facing the camera and the background is bright like the one in your pics.

Are you using a modded VAM with upscaling features? (either through FSR or DLSS).
This is 100% looking like DLSS artifacts.

I don't think I purposefully added any of those effects. I do have ReShade, but it was turned off during tests. It's a rare aberration that ever since my post I've encountered only a few times.

Strange if there would be no "light data" on the skin if I had lights directly on the skin. Last video is case and point on that. You can still see slight jitter noise on the edge where pants end and skin begins. But then again I don't really know what light data constitutes so you might as well be right
