[Bug 34052] The Witcher: Character models are sometimes invisible

https://bugs.winehq.org/show_bug.cgi?id=34052

--- Comment #63 from Freso  ---
attachment 50908 and attachment 51668 both work as workarounds, but the
decisions seems to be to implement this in a toggleable fashion, since there
might be a performance hit. I think we're waiting for either Fever to do more
performance tests or Matteo Bruni to rewrite his patch. Not entirely sure
which.
