[Bug 39180] Witcher 3 Wild hunt Wine 1.7.50 not working

https://bugs.winehq.org/show_bug.cgi?id=39180

--- Comment #51 from Guillaume Charifi  ---
Mh, sorry, I think I read too fast. It is not directly Mesa-related, because it
works fine with nouveau, but indeed probably radeonsi-related.
However, keep in mind that by using wine-staging, it can also be a side-effect
of other patches in the repository. I'll send a trace so that you can check if
there are still artifacts (in which case it would be radeonsi's fault).
