            Bug ID: 99444
           Summary: [radeonsi] The Witcher 3 [Wine] starting menu is
                    distorted
           Product: Mesa
           Version: git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel@lists.freedesktop.org

Witcher 3 main menu distortion (no CSMT)

I'm testing The Witcher 3 with recent Wine staging 2.0rc5 (CSMT disabled),
using AMD RX 480 and latest Mesa devel:

    OpenGL renderer string: Gallium 0.4 on AMD POLARIS10 (DRM 3.3.0 /
4.8.0-2-amd64, LLVM 3.9.1)
    OpenGL core profile version string: 4.5 (Core Profile) Mesa 17.0.0-devel
(git-aac562f112)

Starting screen has distorted text in the menu (see attached screenshot). For
the reference, the game is still unplayable beyond the starting screen and
intro with broken graphics, but users of Nvidia blob report that they don't
have this issue in the starting menu which appears correct to them, so menu
distortion looks radenosi related.

For the reference, to run the game in Wine, you need to set:

[HKEY_CURRENT_USER\Software\Wine\Direct3D] 
"DirectDrawRenderer"="opengl" 
"UseGLSL"="enabled" 
"MaxVersionGL"=dword:00040005

And make sure you are using wine-staging 2.0rc5 or later, since older versions
crash on startup because of the virtual heap limit.

This appears to be Wine related and not caused by Mesa. See

Reopening it, since it appears, that this still can be a radeonsi bug. See
here:

* https://bugs.winehq.org/show_bug.cgi?id=39180#c51
* https://bugs.winehq.org/show_bug.cgi?id=39180#c55

I replayed the trace which works well for other drivers, and I see distortions
with radeonsi (this happens both with Mesa 13.0.2 and Mesa git).

The trace can be found here: https://ufile.io/ed6ac (you can replay it with
apitrace).

The trace works correctly on Intel (Skylake and Haswell).

On radeonsi, I can see the corruption, and there are lots of errors:
118231: message: major api error 2: GL_INVALID_ENUM in
glActiveTexture(texture=GL_COMBINER0_NV)
118231 @0 glActiveTexture(texture = GL_COMBINER0_NV)

They range from GL_COMBINER0_NV (0x8550) to 0x857f, so probably the trace was
recorded on something supporting more texture units than radeonsi? Was the
trace recorded on radeonsi (or AMD hardware at least)?

I didn't record this trace, just reposted it here (I asked the author to
clarify where exactly it was recoreded).

Here is a trace on RX 480 and radeonsi: https://uploadfiles.io/caf8c

Thanks for reporting the issue. I can reproduce it with mesa/llvm git on my rx
480. Needs investigation.

Well, the trace is broken somehow, and it has been recorded using NVIDIA blob
because it relies on NV_register_combiners. That explains the GL_COMBINER0_NV
errors while replaying it.

Could you try that game directly using RadeonSI? Presumably, it should work
fine except if it still relies on NV_register_combiners. And that would be a
game bug.

The second trace I linked: https://uploadfiles.io/caf8c is recorded on AMD
hardware (RX 480) with radeonsi. And the screenshot of the initial report shows
how it looks on actual RX 480 as well. That's exactly how I run it (it's from
the actual game run in Wine, not from trace).

I'm not sure how the other trace ( https://ufile.io/ed6ac ) was recorded - the
author never replied.

And since the game isn't using GL natively, if anything is calling
GL_NV_register_combiners in some situations, it must be Wine.

I just replayed my trace (recorder on radeonsi / RX480), and I see this in the

I can open a bug in Wine about it.

Well yeah, it's definitely unrelated to Mesa/RadeonSI. The app should check if
NV_register_combiners is supported before using it. I'm going to close the
ticket.

Are you sure that NV_register_combiners are used? I haven't checked the trace
myself but I doubt this is a case.

This has nothing to do with NV_register_combiners. It just displayed like this
in apitrace, because GL_COMBINERi_NV = GL_TEXTURE0 + x.

You are right.

The game wants 192 texture units but RadeonSI only exposes 144 (24 per stages),
that explains at least, the glActiveTexture() errors in the trace.

But according to the GL spec, the minimum number of texture units is 80.

[Bug 99444] [radeonsi] The Witcher 3 (GOG/1.31) [Wine] starting menu is distorted

Does the following patch help?

https://cgit.freedesktop.org/mesa/mesa/commit/?id=dfe111368d11aaffae7f8738c858c335cdec1e9d

It actually fixes the glActiveTexture() errors but I still get rendering issues
on my side using the trace.

Can you confirm by running the game directly?
Thanks!

I think that the glActiveTexture() errors are unrelated to any rendering
issues. These are generated by GL context initialization in Wine. It's not
clear to me if they appear when the game is run directly. We bind dummy
textures to GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS_ARB units, so we shouldn't
exceed the limit reported by the driver.

Yes, but according to the trace, 192 texture units were used and the limit was
144 before that commit. As I said, I still have rendering issues (other
issue?). Anyway, it seems reasonable to expose 32 texture units per stage.

I built Mesa from source after that commit, and rendering issues in the menu
are still present when game is run in Wine.

FYI: I just tested it with wine-staging 2.1 with CSMT enabled (that version
allows using it with DX11 already), and corruption in the start menu is gone.
