Hi, in the latest ArcGIS version 2.2.0 and Unity 6000.3.8f1 HDRP there's a weird shadow artifact that shows up on integrated mesh layers when the directional light is at a specific rotation.

In this image a new HDRP project was created and the directional light was set to rotation x: 21.128, y: 16.044, z: 0. No more changes was made except adding the ArcGIS map component and adding the integrated mesh layer.
The artifact seems to follow the z-axis in world space and covers a little more than 50% of the screen when looking along the z-axis.
