Bug ID: 46973
           Summary: Sonic 3 AIR: Black screen; audio and input are working
           Product: Wine
           Version: 4.5
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

      Distribution: ---

Sonic 3 AIR is a fan port of the Sonic 3 & Knuckles game to Windows. The "full"
version was released today, so I tested it on Wine. It seems that the graphics
isn't working; it shows a black screen, but audio and keyboard input works as
expected.

Download at: http://sonic3air.org/
Requires a Sonic 3 & Knuckles ROM image, which can be obtained from Sega Mega
Drive and Genesis Classics on Steam.

This shows up in the console output, which may be relevant:

apitrace of Sonic 3 AIR

apitrace shows an error on glXCreateWindow, so this may be an issue related to
converting SDL's WGL calls to GLX.

Use qapitrace to view the results:

It seems setting "FailSafeMode" in the game's settings.json gets it to work.
I'm still not sure if the regular mode is broken due to a missing GPU feature
or an issue with Wine translating WGL to GLX.

Did you try this game in a real windows box to be sure it is a wine bug not a
game bug?

I don't have access to a Windows system at the moment, but I asked a friend of
mine who has a system with Intel HD 4000 and Windows 10. He said that it works
as long as Software Rendering is forced on. On my system (same GPU, but Wine
and Linux), Software Rendering doesn't seem to affect anything; only
FailSafeMode.

I'm still not entirely sure if this is a Wine bug or if it's a game bug. I did
contact the developer with the API traces and a link to this report.
