Bug ID: 58506
           Summary: Some VST plugins using OpenGL don't render in WOW64
                    mode (black screen)
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: opengl
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

When using yabridge to run Windows VST plugins in a native Linux DAW (in my
case, REAPER), Waves plugins do not render correctly, showing a black window.
The window is interactable (grabs the cursor, can change settings, etc), but
dragging it, closing and re-opening, etc. does not work. In the logs, the
plugins show a bunch of OpenGL errors. This is specifically a WOW64 regression,
since using a build of Wine 10 without WOW64 works fine.

This is what it looks like:
09:07:42 [WaveShell1-VST3 14.12_x64-09EFPegt] [Wine STDERR]
0024:err:opengl:null_glEnable unsupported
09:07:42 [WaveShell1-VST3 14.12_x64-09EFPegt] [Wine STDERR]
0024:err:opengl:null_glBlendFunc unsupported

(Sorry for pasting it here, I have read the rules, but it's not letting me
paste text as an attachment for some reason :/)

Are you referring to the experimental WOW64 mode? Attaching the console logs
would make things much more clear.

You also need to upgrade Wine to the latest release.

Yes!

I have attached the full log.txt file, however the logs don't have much more
info than the few lines I've pasted in the description - it's just a bunch of
OpenGL errors.

I am on the latest release! I tested this with wine-tkg and wine-staging from
the Arch repos, both on version 10.12. When downgrading to a prior version of
Wine, before Arch switched to WOW64, everything went back to normal again.
