HDRP Shadows of Alpha clipped meshes jitter with changing directional light

We have an issue where we get shadow jitter in HDRP. Happens when the sun (directional light) gets moved, which causes the shadowmap to update. Tried a number of settings and corrections to no avail.

Well, ended up fixing it. Had to do with the (camera) lighting volume shadows - specifically the cascade count. Needed to be tweaked significantly. The closer splits need to be smaller, to fine tune the shadows you can see nearby. 170784-cascade-splits.png
