[Bug 17637] New: Gothic III: Flickering black/textured polygones at some places

http://bugs.winehq.org/show_bug.cgi?id=17637

Summary: Gothic III: Flickering black/textured polygones at some
                    places
           Product: Wine
           Version: 1.1.15
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: directx-d3d
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

At some places in the world of Gothic III, especially at towns (places with
many objects), there are polygones in the air which are either black or
textured. They are not "steady", changing the camera view and moving the hero
makes them flicker, move or change. Textured polygones are more steady and more
solid than black ones.
Looking at these polygones decreases performance of the game, the more of them
is visible, the lower the performance.

I *think* (im not sure) the appearing of these polygones is related to this
error message:
fixme:d3d_shader:shader_glsl_select >>>>>>>>>>>>>>>>> GL_INVALID_OPERATION
(0x502) from glUseProgramObjectARB @ glsl_shader.c / 3584
which obviously doesn't say much (... or does it do?).

The polygones appear with both fbo and backbuffer offscreen rendering method.
With fbo, performance decrease is, as far as i can see, worse.

The problems are acceptable in the desert, in the ice part of the world, and
generally outside towns; towns in myrtana are kind of unplayable, full of these
things. Here's a screenshot:

Created an attachment (id=19891)
 --> (http://bugs.winehq.org/attachment.cgi?id=19891)
+d3d_shader log with nvidia geforce 6600

Confirming the problem with a geforce 6600, driver 180.29.

Attached is a +d3d_shader log where the problem was visible.

This bug isn't visible with a 8800GTS and the same driver.

The problem looks like this:
fixme:d3d_shader:print_glsl_info_log Error received from GLSL shader #205:
"0(32) : error C1068: array index out of bounds\n0(33) : error C1068: array

bounds\n0(69) : error C1068: array index out of bounds\n0(87) : error"...

and the related shader:
...

Yes, that's the same basic issue. (And for a part, 17437 as well.)

Is this still an issue in current (1.1.30 or newer) wine?

As far as I understood this issue, it's related to some basic wine structures
and can't be fixed for older graphics cards. For newer cards, it shouldn't
occur however.
But I'm not a developer, I don't know exactly. :)

Sven

It is still an issue in Wine 1.1.40?

As i said in my previous comment, I don't think this issue can / will ever be
fixed. It should not occur with newer graphics cards like, I guess, GeForce
8xxx or later neverthereless. That's all I know...

Sven

I didn't want to use question mark. I only wanted to say that on NVIDIA 9xxx
it's still an problem in Wine 1.1.40.

This is a duplicate of bug 7991. But I haven't checked if it is still present
with a geforce < 8000.

The rendering looks fine with a geforce > 8000. (There are no "Flickering
polygones")

Please don't mix this bug with some z-figthing issues as could be seen here
http://bugs2.winehq.org/attachment.cgi?id=20131 on geforce > 8000
