[Bug 14975] New: Word of Warcraft 3.01 Beta Wotlk

http://bugs.winehq.org/show_bug.cgi?id=14975

Summary: Word of Warcraft 3.01 Beta Wotlk
           Product: Wine
           Version: 1.1.3
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: opengl
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

There is a graphical problem with an effects of the beta client of wow...
The problems is present only if opengl engine is used, with d3d engine this
problem is not present.
Some area of the game and some quest of Death Knight starting area are affected
of this problem, this graphical effect create a sort of mist around the screen,
and use a sort of blur, with opengl all those effects make the screen all white
or all black, only menu are visible and game stil go without crashing.
I tried it with 1.1.2 and 1.1.3 version of wine. The only workaround is to use
an old version of wine (0.9.46)

Tried on an nvidia 8800gt with 169.12 driver version (ubuntu 8.04 nvida default
restricted driver) and with compiz disabled....and I'm not the only one to
suffer of this bug, you can read comments and test about it here...

OK - I set WINEDEBUG=+wgl started to WoW, logged in, got to the point where
everything went black. There's only one problem: the output is 4.7MB... any
ideas how I can get the log a little smaller so that I can upload it here? :-)

Quick & dirty hack, that provides a workaround

You probably have to replace the fmt_id (0x77) with another value (see glxinfo
-t)

Looks like it is the pixel format indeed. I've added a quick and dirty hack in
dlls/winex11.drv/opengl.c, that includes only the format with id 0x77 in the
list, that has an alpha channel with my video card:

Without the patch the format 0x75 is used (no alpha channel => white screen).
With that screen effect works. I just don't know how to make a usable patch out
of it, so that the format with alpha channel is preferred... ;)

hack

I didn't have much time the last couple of weeks to reply here but I knew this
was the problem but it is far from easy to fix. In short the issue is the
function ChoosePixelFormat which is used by programs to select an opengl pixel
format. The function is very bad as it doesn't give you ANY guarantees. For
example if you would ask for a pixel format with 32-bit colors, it could return
one with 8-bit if 32-bit isn't available. In this case WoW only asks for 32-bit
colors and specifies 0 for red, green, blue and alpha while it seems to want
alpha after all. It is trivial to modify the algorithm but it easily breaks
dozens of apps. I need to properly analyse the pixel format table of multiple
windows drivers again (I had to do this before but wasn't able to discover a
pattern in it) and need to do lots of tests. For now you could add a hack like
the one I just added.

Updated hack.

This workaround hack disables all pixel formats without an alpha channel, so
you can use a single wine installation for all your apps and just set
WINE_WGL_OPENGL_ONLYALPHA_HACK when you want to play World of Warcraft.

$ export WINE_WGL_OPENGL_ONLYALPHA_HACK=1
$ wine /path/to/WoW.exe
$ unset WINE_WGL_OPENGL_ONLYALPHA_HACK

or

$ WINE_WGL_OPENGL_ONLYALPHA_HACK=1 wine /path/to/WoW.exe

--- Comment #23 from Roderick Colenbrander   2008-09-20 14:49:50 ---
I did some tests on various windows opengl drivers and tested what the same
ChoosePixelFormat call wow makes returns, so one with colorbits=32 and the
other bits set to 0 and DoubleBuffering, DrawToWindow, SupportOpenGL and RGBA.
In general it returns a format with r=g=b=8, alpha=0 and further the flags that
were requested and so now and then even depth and stencil. I have the
impression that it might not be the ChoosePixelFormat call which is the problem
(unless the driver is doing some evil fixups).

I have the impression that the display driver is doing some evil fixup or so OR
it could be that wglChoosePixelFormatARB selects a format with alpha. You would
have to hack the code to see whether it is the alpha which matters for the
window or for the pbuffer (it selects pixelformat 1 for the window and 9 for a
pbuffer).

Since Jorge his hack worked and mine not I would guess it is related to the
wglChoosePixelFormatARB call but for that no alpha is requested either.

Actually the ChoosePixelFormat call can be ignored at all as I think it
originates from WineD3D. A long time ago there were other WoW bugs and I
remember WoW using ddraw at startup to figure out the amount of videomemory.

I don't have an ati, but I find out that wotlk with opengl don't work at all
with an ati.
this is the bug http://bugs.winehq.org/show_bug.cgi?id=15449

Blizzard "fixed" the problem in the latest version.
It just doesnt use the fog-effect anymore in opengl mode atleast.
Tried several quests that had the effect before and its gone now.

Just curious: did you test before the beta-servers went down? And the beta was
3.0.2 before shutting down this week while the live servers were 3.0.3 and this
effect could only be seen in Northrend and the death knight's starting area...

This isn't possible right now since there's technically no way to reproduce the
bug until the WotLK release (the 13th). Though, are you sure they just disabled
the effect under OpenGL? I don't recall any error under the Mac OS OpenGL
version.

Check if you didn't have ffxSpecial set to 0.

The issue was that WoW required an alpha channel for this effect but didn't
request one. It would have been a single line fix for WoW its win32 opengl
code. The log would show if they fixed this issue which is very easy for me to
see.

Tried it with ffxSpecial "1" now but didnt notice any change.
Guess blizzard removed it for openGL users.

ffxSpecial wasnt in my Config.wtf before, does it do anything special?

Blizzard indeed removed it for OpenGL. Shame.
ffxSpecial is just a special CVar that disables this effect. See
http://www.wowprogramming.com/docs/cvars for more.

Please close this bug for now, since there is no way to verify it.
