--- Comment #5 from Mikko Niemelä mikko.niemela@gmail.com --- Created attachment 59644 --> https://bugs.winehq.org/attachment.cgi?id=59644 Partially invisible character model
This is how a character model that has transformation effects looks like. This seems to happen to NPCs that undergo some kind of transformation (changelings, vampires, or otherwise magically disintegrated) and it has an effect that causes them not to render correctly.
Not entirely sure if it's the same bug since some parts of the model are still visible.
