I'm testing on an iMac running 10.10.5 using wine-1.9.21-143-gb22aa57 (current
git).  I see a window, but its content is just black.  You're not seeing any
part of the window at all, other than the title bar?

Are you testing with a fresh prefix?

I see the fixme and second err logged one time (and they are due to a known but
not serious problem), but I'm not seeing the first err and the messages are not
repeating.

What model Mac do you have and what GPU does it have?


Anyway, the problem seems to be that WineD3D is using a double-buffered pixel
format when it's only rendering to the front buffer and, maybe, never flushing.
 And/or it's falling afoul of a bug in macOS's OpenGL implementation.  If I
apply the hack in attachment 55968 from bug 34166, the game renders properly.

Alternatively, a workaround that doesn't require building a patched Wine is to
set this registry key:

[HKCU\Software\Wine\Direct3D]
"DirectDrawRenderer"="gdi"
