Close range lighting has white fog effect

[Imperator_Urist]

After a bit this weird close range white fog starts to be rendered onto nearby objects, if they're far enough outside the range they look like they have the normal lighting.
Doesn't happen right away happens after a bit and changed a few settings and not sure what one might be the cause.
Build mode doesn't seem to suffer from it either.

That's a bug with the Build Mode flashing thingy.

I usually "fix" it by getting out, getting in a core, entering build mode and waiting for the flashing to stop, then getting out of that core and getting back into my build project.

i fix this by going to options -> graphics and then turning "Simple Lightning Quality" on and off again. After this, the white fog suddenly disappears for me.
