Flickering shadows

Hi! I recently upgrade my project to HDRP, and I have a problem with the directional light realtime shadows. Their quality continues to abruptly change without any transition for about 0.5 second after the camera stopped moving. It looks like flickering. And It is only in the build (not in the editor player mode). The walking in the forest in sunny weather looks bad due to that.

I didnt have this problem with the shadows when I used realtime shadows in built-in render pipeline. I guess it may be an issue with the performance of HDPR shadow atlases?

How to get stable and smooth non-flickering realtime shadows like in built-in? Thank you.

Can you record a short video to demonstrate the problem?
