This is a picture of what is happening. I've tried swapping all of my clothes and weapons in case some of them had an odd effect. I haven't installed any mod that should do this (I have a generator quieting one, a body hair one, the full sentence dialogue, some texture replacements, and pip boy shadows).
Sometimes it vanishes while in dialogue but most of the time it's just like this on everyone it's driving me mad and ruining my screenshots. Can anyone help me out with this?
