Im using the DX10 fixer and REX cloud textures, plus the ASN weather engine. On a number of occasions when clouds are hanging low in mountain areas, I get flickering between clouds and mountains. I assume this is some kind of shader issue? Any known way to fix this?

engine limitiation that only volumetric clouds could solve = impossible.

Gotta live with it, for anyone flying near the Alps it's a major show stopper.

Only solution is to raise your lowest cloud layer to an altitude above the mountains you're flying over/next to.
