Mosaic like lighting results using Adaptive Probe Volumes (APV)

I get extremely weird result like that:


When I try to bake my APV. I´ve changed barely no settings except enabling Sky Occlusion + Direction and settings my sun´s shadows and contact shadows to Ultra and High.
Is there some hidden settings to de-mosaicify or is that just a bug. Thanks!

Edit:


The probes also seem off, although I have assigned my static meshes correctly.

Switching to DX11 fixed the issue, might be hardware related? Im using an AMD Radeon 7800xt.

The issue reappeared on DX11, tried 6.1, first bake works then it starts to look like this again. Am I doing somethings wrong?

Vulkan, DX12 seem to still not work, is there any other fix, instead of using DX11?

Sky occlusion spots the scene if the environment lighting samples are too low in the lighting panel, there is a “blur” effect in the APV… options? Object that allows you to further smooth it as well
