Bug Bug in Shadows Rendering with Alpha Clipping

Hi

We built some trees with branches and leaves that are using alpha clipping. I had to update the project from 2021.3.xx to 2022.2.xx because in the previous version the WebGL data caching has some issues and doesn't work in built applications.

Since when I updated the project to 2022.2.xx I have a clear problem with these trees shadows where the alpha clipping isn't working properly. In the webGL build, the shadows are coming from the not-clipped branches, having this result:


In the Android/VR application it is even worse, since the shadows changes depending by angle, also from the Scene View other than the Game View. These are the two shadow states that occour when changing camera angle:


Does anyone have any experience on this ? Any workaround ? The one only thing I can think about is having two trees for every tree, where one is without alpha clipping, renders only shadows, and the other one is the visible tree with alpha clipping and no shadows.
It is DEFINITELY not so professional and i'm looking for a better way.

 

This is maybe the same problem? https://forum.unity.com/threads/urp-shadow-flicker-after-upgrading-to-2022-3-1f1-lts.1448665/

No solution, but more exposure at least. If this isn't the same problem, then it's at least a very similar one.

I also have a lot of vegetation with alpha clipped materials in my game and I'm seeing all these issues.
