I bet that's it.

In the regions where the background is unobstructed, the fog is calculated
once and is made to be 50% (or so) transparent.

But in the regions that are split by a transparent object, the fog is
calculated in front of the object to be 50% transparent, and then again
behind it, for a final transparency of 75%, making it darker.

You may just have to remove the transparency. You can compensate by
increasing the distance value, and if you want the sky to be visible you can
use a ground fog.
