[Bug 10833] New: WoW indoors/instance white characters. Vram problems?

http://bugs.winehq.org/show_bug.cgi?id=10833

Summary: WoW indoors/instance white characters. Vram problems?
           Product: Wine
           Version: 0.9.51.
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-x11driver
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

When the latest wine went stable 0.9.49 (also tried .9.50, .9.51) I upgraded,
along with the 2.3.0 WoW update.

I had had a problem long ago where going indoors would cause characters
(persons (i.e. not letters)) would turn bright white (with no textures), also
some objects would lose all textures. This problem was once dismissed by
"ensuring" X that I had enough Vram ("VideoRam    128000" in my xorg.conf).

With the most recent update of WoW (I even tried downgrading wine) the problem
has resurfaced. I have added these ram options in user.reg:

[Software\Wine\OpenGL] 1197730869
"DisabledExtensions"="GL_ARB_vertex_buffer_object"
"VideoMemorySize"="200"

[Software\Wine\Direct3D] 1197775965
"PixelShaderMode"="enabled"
"VertexShaderMode"="hardware"
"VideoMemorySize"="200"

Dxdiag.exe also seems to report the correct amount of Vram.

Thanks
-Ian

Note: This is happening in both the opengl and directx modes, and only on my
laptop (VGA compatible controller: Intel Corporation Mobile 945GM/GMS,
943/940GML Express Integrated Graphics Controller (rev 03)).

Wine's D3D is layered on top of opengl and there should not be any memory
problems. Also in opengl mode, WoW uses dirert3d to query the amount of video
memory, so that explains why both opengl and direct3d can have the same issue.
Personally I think that your problem is a driver bug. Especially normal opengl
mode shouldn't be affected by memory issues as once there is not enough memory
infrequently used textures for instance are moved to system memory. Sure this
can lower performance but it shouldn't crash.

Invalid... nope.

"Personally I think that your problem is a driver bug." A driver bug that
miraculously appears without changing the driver... DOH! (notice the only
upgrades are wine/wow)

It turns out that is (probably) in fact a wine BUG. Enabling Character shadows
causes the characters to return to normal when in an instance or indoors. I
would think that this would be totally the opposite behavior as having the
character shadows should increase the demand on the system (more ram to hold
shadow textures?) not decrease the demand...

Could this be fixed? I am fully able to recreate this on my hardware (over and
over again). I would like to run without character shadows as it should
increase my frame rate (ever so slightly mind you) on this under powered
machine. I would be happy to provide further information on request.

Thanks,
-Ian

Driver bugs can surface with all strange changes. I once had a driver bug show
up with changes in code that was never executed(-> uninitialized variable in
the driver). You don't have to change a driver to trigger a driver bug.

If you're running the game in OpenGL mode, the chance of a Wine bug is rather
rare, except if the game doesn't initialize GL at all. Beyond initialization,
we're just 1:1 forwarding the calls. There isn't much to do wrong there, and
even less we can do to work around driver bugs.

You say you're using the Intel driver, which is part of Mesa. In this driver I
have seen many memory corruptions and other problems.

/agreed
Although I find it funny that disabling some textures here or there (although I
will admit that I know nothing about what is going on under the hood here)
would cause such an issue... I have seen some of the strangest things with this
driver myself.

I will leave the bug as UNCONFIRMED, and will leave the decision to the experts
(you or your colleagues). If there is a lack of hardware, and someone would
like to find the root cause (i.e. determine if wine is at fault) I would be
happy to assist with my hardware.

Thanks Again... You guys/gals are doing a valuable service! The community is in
your debt.

P.S. If some one would like to comment on what is happening here (i.e. give
insight). I would also like to open a bug against the intel driver. I would
just like to be a little more informed before I go over and write another
possibly invalid bug. Cheers

Is this still an issue in 1.0-rc3?

I am not sure... Does anyone have access a video card equivalent to this:
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS,
943/940GML Express Integrated Graphics Controller (rev 03)
00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS, 943/940GML
Express Integrated Graphics Controller (rev 03)

I no longer have a WoW subscription therefore I am unable to test rc3. Feel
free to change the sev or resolution as needed.
