Sun glow visible through opaque geometry

Hi, I’m using a directional light with SkyAtmosphere and getting this issue while the sun is hided by opaque meshes :

What you see in the middle of the screen is the sun behind a mountain. Happens with landscape but with any opaque mesh too. The only thing that stops it is to turn off aerial perspective in SkyAtmosphere by setting “aerial perspective view distance scale” to zero but is obviously needed (at least at 1)
