PBR Shader Graph Incorrect Shadows

I encountered an issue recently with shadows here where strange shadow culling is occurring.

I’ve tracked the issue down to materials using PBR Shader Graph shaders. Upgrading my HDRP project from 2019.1 to 2019.2 or later breaks the shadows for any material using a PBR Shader Graph.

Using a Lit Shader Graph doesn’t exhibit the same problem.

I have the same problem. I am using a pbr graph triplanar shader and these shadows appear when the angle of the directional light is extreme against the object. This only seems to occur with directional lights.
