I have been googling all day, literally, trying multiple things, like: drivers, reinstalls, various mods including the ingame respec mod and a few others in the steam workshop (Fort Joy mirror+portable mirror). I finally got to the ship and wanted to respec (only point distributions, not looks!), and now all portraits get bugged similarly - even when i just click the mirror then cancel everything. My main is Lohse, and her portrait is partially white/grey covering entire face and hair area.
So i just bought the game on Steam and am playing through DE version.
