iv had this same issue before, i find that increasing the quality helps at the cost of a lot performance. i think a easy fix for this would be to add a option to blur the fog ( like with shadows and block lighting ) to reduce the noise.

until null sees this and fixes this tho there's no easy fix.

volumetric fog already has a post-blurring option; it just doesn't work as well on a 3D volume as it does 2D surface shadows.

And yes, then only fix is to increase quality so it traces smaller steps. What you're seeing is the dithering applied to keep the low sample count from showing "ghost copies" of the actual scene.
