--- Comment #18 from Andrew Church  ---
Created attachment 53985
  --> https://bugs.winehq.org/attachment.cgi?id=53985
Proof-of-concept patch (for wine-1.9.5)

I've confirmed this fixes FFXIV (at least in the character creation screen),
and I don't see the artifacts reported in the Unigine Heaven benchmark in
comment #15 with this patch applied.
