Angle dependent noise at the edges of ray-traced screen space shadows (HDRP)

Hi all,

Does anyone know why the noise at the edges of ray-traced screen space shadows in Unity’s High Definition Render Pipeline depends on the angle of the shadow casting object to the point light source?

At 0°, 90°, 180°, 270° and so on the shadow edges contain almost no noise but at 45°, 135°, 225° etc., you get what you can see on the screenshot above. BTW: I am using Unity 2020.3.26f1

No one? Can anyone at least confirm if this is intentional behavior or a bug?
