[Bug 27194] New: The Witcher 2: White/coloured screen with UseGLSL=enabled

Witcher 2 - GLSL enabled - 01

As summary, during gameplay screen is white and/or coloured in a glitchy way.
Screenshots will be uploaded to show this more clearly. The main error seems to
be this:

err:d3d_shader:shader_glsl_select >>>>>>>>>>>>>>>>> GL_INVALID_OPERATION
(0x502) from glUseProgramObjectARB @
/var/tmp/portage/app-emulation/wine-1.3.20/work/wine-1.3.20/dlls/wined3d/glsl_shader.c
/ 4625

Additionally, setting "UseGLSL = disabled" works around the issue.

--- Comment #6 from Silver  2011-07-04 08:16:02 CDT ---
I can shed some additional light on the problem.

The GL_INVALID_OPERATION from the original description is actually not the real
problem. Instead it's just the cause of a failed shader compile. The reason why
the shader fails is because it contains illegal code. Looking at shader object
8 from the attached log it's apparent that the generated shader code uses
sampler variables which hasn't been declared.

For example the error on line 94 corresponds to the line "R5.xyzw =
(texture2D(Psampler5, R1.zw).xyzw);". Only Psampler[0-3] are defined!

Disabling GLSL isn't a real fix either because ironically the generated ARB
shader also contains errors. (It's possible that nvidia is able to cope with
these errors more graciously than AMD).

Because the error originates from the generation of the OpenGL shader, this is
clearly a wine bug and totally unrelated to any hardware driver.

A short description of the bug could be: "Error during conversion from DirectX
shader to OpenGL shader".

I tried to locate the bug in the wine source code. But even though I know in
which files to search for the problem, I'm not familiar enough with the source
code to be able to pinpoint the relevant locations.

Currently the latest git version is still effected by this bug.

I've added line numbers to the GLSL output and I exit the program as soon as
shaders has been dumped. The OpenGL compiler errors are generated from a
slightly outdated version of the fglrx driver.

The game seems to be creating a pixel shader through
IDirect3DDevice9::CreateVertexShader(). Surprisingly, this almost works, but
the shader then runs into the vertex shader sampler limit of 4. To confirm,
could you create a new log, with WINEDEBUG="+d3d9,+d3dx,+d3d,+d3d_shader"?

Looks like it really does create the pixel shader as vertex shader. It may take
a while to fix this. As a quick hack you could perhaps try raising the sampler
limit ("shader->limits.sampler = 4;") in vertexshader_set_limits().

Spot on. Increasing the limit to 8 bypasses the problem.

I didn't test anything excepts the starting menu and the intro logos and so far
everything is much much smoother than before. Before it was lagging a bit and
the sound was interrupted. Now it's all smooth. Fixing this bug might actually
fix all known bugs for this game so far.

Is this a wine bug or is the game doing things wrongly. Maybe it would be worth
it to send a notification to the developer.

Anyway, great work finding the cause and providing a temporal fix. I'm much
obliged. :)

I just tried raising the vertex shader sampler limit to 8 (and also 16) but
although it does reduce the severity of the glitches, they are still there
(once you get in game). Screenshot and log will be uploaded shortly.

I've now done some additional testing. Without the hack I'm not able to start a
new game. With the hack the games start but it look really ugly. I also did a
test on a different machine with similar results.

Finally I did a test with the open source radeon driver and noticed something
peculiar. The same shader (object #8) fails to compile even with the hack. The
error message it generates are the following

error: no matching function for call to `texture2DLod(sampler2D, vec2, float)'

The generated shader is compiled as a fragment shader and as such according to
the specification can't use any of the Lod functions. After taking a closer
look at the shader I found that the shader also uses gl_FragCoord which is a
strictly fragment shader variable.

The generated shader code therefore contains restricted elements of both a
fragment shader and a vertex shader. Strictly speaking, it should be impossible
to compile it on any compiler.

Yes, but ARB_shader_texture_lod lifts that restriction. Which driver is that
exactly? Current versions of r300g and r600g should support this.

r600g. Maybe my version is outdated. I haven't been able to compile a 32 bit
version of mesa since r300 started to depend on the LLVM. Things would have
been much easier if wine had been using the 64 bit version of the driver.

As it turned out, when I updated to the latest Ubuntu version I forgot to
re-insert some environment variables and was therefore still using parts of the
default version.

Now I've updated my build procedure and removed some deprecated variables and
was able to build an updated 32 bit version of mesa. The bad part is that I'm
no longer able to test the shader compiler since the new git version almost
immediately crashes my computer when I start this game.

I'll run a regression test and open a new bug report if it's unrelated.

No, this is the same issue. The application creates a vertex shader, then tries
to use it as pixel shader. It's just caught earlier now.

Looking at dlls/d3d9/shader.c:

In "IDirect3DPixelShader9Impl
*unsafe_impl_from_IDirect3DPixelShader9(IDirect3DPixelShader9 *iface)" line 312
is:

assert(iface->lpVtbl == &d3d9_pixelshader_vtbl);

simply commenting out this line will allow you to run The Witcher 2 as before
with GLSL disabled. Not a real fix, but I'm not familiar enough with Wine code
to do much else. I was just tired of not being able to test the game at all
with newer Wine builds.

Refuse to create a vs from a ps source (and the other way around)

Some testing seems to show that the bad CreateVertexShader call should simply
fail (presumably the game expects that). Can someone try this patch and report
if it helps or not?

with 1.3.27. Currently able to play at stock Ultra minus UberSampling (and
Cinematic DOF since that caused a draw issue before and I wasn't testing it for
this purpose) using 1600x1200 (when my new monitor arrives I'll try 1920x1200).
Framerate is smooth/high to playable even in situations where it would
previously be ridiculously slow no matter the setting.

Hardware is similar. Q9550@3.09ghz, EVGA GTX 460 768MB SuperClocked, and 4gig
of ram.

Tested this with GLSL enabled and had the same result as disabled. Nice work.

It helps!

The patch works for me although it seems like some other part of wine has
regressed since last time I tried. The starting menu have weird names and the
game no longer shows the dialogues.

I tested against git yesterday and saw nothing of the sort... Everything was
as-normal.

I reinstalled the game, just in case, and now it works again.

I say this is fixed as of latest git. There's a slight performance difference
with Enabled vs Disabled but that has no bearing on the fact that graphically
it's virtually flawless either way.
