Bug ID: 54994
           Summary: Problem with Dolphin emulator "X Error of failed
                    request: GLXBadFBConfig" and OpenGL < 4.6
           Product: Wine
           Version: 8.6
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2

Hi all!

Here follows a new bug report regarding a "X Error of failed request:
GLXBadFBConfig" error in conjunction with the dolphin emulator. This problem is
present for me since Wine 8.6 and Mesa 23.2.0-devel (git-483639d 2023-04-24
jammy-oibaf-ppa).

It is unclear if this is a Mesa or a Wine bug. Originally this was reported at
the Mesa issue tracker here:
https://gitlab.freedesktop.org/mesa/mesa/-/issues/8901

Maybe someone from the Wine project can bring more clarity where the problem is
coming from. ;-)

Note, this issue is similar to old bug 50859. But in contrast the underlying
problem does not affect all applications. I was only able to reproduce this
issue with the dolphin emulator.

A workaround is to add "MESA_GL_VERSION_OVERRIDE=4.6" and override the reported
OpenGL version to 4.6. Interestingly this even works with OpenGL 3.3 based
hardware like an Intel HD 2000 iGPU. And this is only valid for OGL 4.6. A
lower OGL override like "MESA_GL_VERSION_OVERRIDE=4.5" has no effect.

A new addition.

This topic here depends on the used application. So the dolphin emulator has a
minimum requirement for OpenGL 3.3 while it supports up to OpenGL 4.6. Ergo, I
had to expose OGL 4.6 to get it working. That also explains why the PCSX-Redux
emulator is not affected, it only has support for OpenGL 3.x. As a result it
can be said that this `GLXBadFBConfig` error here depends from the application.

If the application supports a higher OGL version then the system exposes then
the error is present. But when the OGL requirement of the application is within
the available OpenGL version then there is no error. As a consequence I think
this looks to be more a problem in Wine rather then Mesa.

So finally this problem should be not present on modern systems which usually
support OpenGL 4.6. On the same time this problem should be reproducible by
exposing a lower OpenGL version than the application supports. So in
conjunction with the dolphin emulator 5.0-16391, a
"MESA_GL_VERSION_OVERRIDE=4.4" or "MESA_GL_VERSION_OVERRIDE=4.5" override
should trigger the "X Error of failed request: GLXBadFBConfig" error.

Diff to work-around the Mesa issue

I believe this is more likely a Mesa issue than a Wine one as I described at
https://gitlab.freedesktop.org/mesa/mesa/-/issues/8901#note_1940408. However,
fixing Mesa appears difficult. Is it acceptable to work-around the Mesa issue
in Wine (see the attached diff)?

Hello, I have been facing a similar issue for the past couple of months
I am on Fedora Silverblue 38 and use Lutris Flatpak to play games
I am on a 3rd-gen Ivy Bridge platform with IntelHD 4000
Some of my games broke after what I believe to be a Mesa update in Flathub
Particularly, I am most concerned with the reVC windows executable, As I like
to play GTA - Vice City alot.
Previously the game launched and played just fine, but after the Mesa update it
fails to launch with the following error :

X Error of failed request:  GLXBadFBConfig
  Major opcode of failed request:  152 (GLX)
  Minor opcode of failed request:  0 ()
  Serial number of failed request:  276
  Current serial number in output stream:  276
Monitored process exited.
Initial process has exited (return code: 0)
Exit with return code 0

Googling online with the error has brought me to multiple archwiki and wine
threads

I am certain this is most likely a Mesa issue as the reVC windows executable
will work fine in Debian 12 with native and older wine and Mesa but neither on
Fedora 38's native wine with updated Mesa nor Lutris's flatpak with flathub's
Mesa

I would like to offer more logs/help in anyway I can.

Does the described workaround works in your case?

Regards.

Okay folks, it is confirmed meanwhile that this problem here is a 100% Mesa
one.

There exist also already an MR which will fix this "GLXBadFBConfig" problem:
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/23762

The mentioned workaround via a GL override like "MESA_GL_VERSION_OVERRIDE=4.6"
seems to work in my case with the dolphin emulator. But it is also confirmed
for example regarding Lutris that this tweak results in a black screen. Ergo,
it is in general not a good idea to override the GL version because it might
introduce other problems. ;-)

Maybe I should close this bug report here. Will do that when Mesa MR 23762 has
landed.

Yes. Please do close the bug once it is fixed.

Resolving NOTOURBUG while the upstream bug is still pending.

The workaround only works in some instances in my case when using wine via
Lutris Flatpak, yes my issue is not related to Dolphin emulator but the error,
timing and also probably the cause is same too

Hello,

In general, it's best practice with Wine to install applications in separate
wineprefixes, so that workarounds and specific settings required to make one
app work don't break other apps.

When the MESA patch lands you may update and retest with it and hopefully your
issue will be resolved too, but if it's not, we don't give support for issues
with Lutris here so you'll have to retest your apps with only plain
wine/wine-staging, or file a bug at Lutris support.

Regards.

Mesa MR 23762 landed recently. It is confirmed that the GLXBadFBConfig problem
is effectively resolved.

So no GL override workaround is needed anymore. ;-)

Note, while Mesa MR 23762 has fixed the GLX problem in conjunction for recent
libx11 versions it may break the creating of contexts if libx11 <1.7.4 is used.
That seems to be an other problem of libx11. Affected users have to update
libx11 to a version >=1.7.4 to resolve that issue.
