Bug ID: 54787
           Summary: Penumbra: Overture in game black screen with enabled
                    Anti-Aliasing (multisample)
           Product: Wine
           Version: 8.3
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: d3d
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

How to reproduce:
1 - Download Penumbra: Overture game in Steam
2 - Enable the game compatibility setting "Force the use of a specific Steam
Play 
    compatibility tool"
3 - Set all the game settings to high (The important is "anti-aliasing" setting
= 4 and "Post Effects" = on and "Bloom" = on)
5 - Run new game.

Actual result: Black screen rendered

It can't be reproduced for pure windows on windows version and native linux
version on linux

This bug was observed while implementing workaround for "mesa" project:
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/22147/diffs?commit...

The bug reason in GL spec (8.7): 
"An INVALID_OPERATION error is generated by CopyTexImage*D"
"the effective value of SAMPLE_BUFFERS for the read framebuffer
(see section 9.2.3.1) is one."

BUT

Windows version on Windows OS uses just wglChoosePixelFormatARB call with
WGL_SAMPLES_ARB argument 
And game has common GL_SAMPLES = 0 and arb WGL_SAMPLES = 4

Probably WGL_SAMPLES does not have the multisample restriction but `wine`
translation breaks this

When wine translates it to a Linux it uses explicit renderbuffer with samples

And the default GL_SAMPLES value for `wine` is 4

And the GL spec restriction works in that case

Eventually I've found that the issue is related only to a Valve patched fork of
Wine

So the 'pure' wine does not have the issue

Created PR which fixes this
