Description i.kalvachev 2018-03-09 21:52:45 UTC

Running Portal, HL2, HL2_LC, L4D2 using wined3d results in black screen. Other than that the games seem to run fine - I can hear the menu sounds. The Steam Overlay also works and displays fps counter and notifications.

In the terminal the following message could be seen:
"00c1:err:d3d:wined3d_debug_callback 0xf399120: "GL_INVALID_OPERATION in glUseProgram(program 7 not linked)"

The problem happens only with the Mesa3D-18.0 branch. I've tried rc4 and rc1.

Everything works properly with Mesa-17.3 and git master from Feb 23 ( 8df11f3fad52507266ca1e97149fd4175ad05471 )

Gallium Nine and native Linux OpenGL versions of the same titles works fine.
I'm with AMD HD5670 - Evergreen Redwood card (R600 driver).

Comment 1 i.kalvachev 2018-03-09 23:50:31 UTC

The problem appears with Wine-3.0rc1 or newer (including Wine-3.3).
It does not appear with Wine-2.22.

Please attach the full terminal output.

Comment 3 i.kalvachev 2018-03-10 11:17:45 UTC

Created attachment 137961 [details]
terminal log of "MESA_GLSL=dump R600_DEBUG=nosb,vs,ps wine steam.exe"

I'm attaching full log created with
"MESA_GLSL=dump R600_DEBUG=nosb,vs,ps wine steam.exe &> glsl_error.log"

The most relevant line in the output seems to be this one:

"error: declarations for shader output `gl_BackSecondaryColor` are in gl_PerVertex and gl_PerVertex"

It looks like the bug is not related to the R600 driver, but to the glsl-compiler.

Comment 4 Emil Velikov 2018-03-12 17:04:52 UTC

Bisecting the issue to the offending commit would be a good move.

A small shader test [1] for piglit will also be a nice move. Thus one can easily reproduce and + ensure it doesn't happen in the future ;-)

Comment 5 Józef Kucia 2018-03-12 20:16:26 UTC

error: declarations for shader output `gl_BackSecondaryColor` are in gl_PerVertex and gl_PerVertex

It looks like the same problem as bug 104668 and bug 104777.

4195eed961ccfe404ae81b9112189fc93a254ded fixes the problem.

Well, this is kind of expected, because the current git master does not have that bug.

However, the real bug I am reporting here is that
the above fix is not ported to the Mesa3D-18.0 branch.

You definitely do not want to make a release containing that bug.

I cannot reproduce the bug anymore.
Looks like it is fixed.
