[Wine] Odd behavior in World of Warcraft

[Daniel Burke]

I am just messing around with wine and World of Warcraft, I am behind a
firewall and presently unable to get out to WoW, but can get to the login
screen fine.

The problem is that I can run it with a clean .wtf (config file) and it
starts up ok with defaults (DirectX mode) and seems smooth, I exit and then
launch it again and it seems to "stutter" and I dont mean sound, but
graphically.  It will run, say 5 frames smooth then "stutter" 5 frames fine,
"stutter" indefinitely.

Since it is in DirectX mode the hardware cursor is on, but when it stutters,
even the mouse cursor freezes for this fraction of a second.  I can restart
the X server and it runs ok the first time, stuttery the next.

The output from wine (different PC so I cannot copy/paste) is the same both
times, I do notice some GLSL errors like this:

fixme:"Vertex shader was successfully compiled to run on hardware"
fixme:"Vertex shader(s) linked, no fragment shader(s) defined"
fixme:"Fragment shader was successfully compiled to run on hardware"

WARNING:"extension 'GL_ARB_draw_buffers' not supported"

I am guessing these errors might be related to the problem.  My hardware:

LG P1Express Dual laptop
1g DDR2 RAM
Core Duo 1.8 CPU
ATi X1400 video card (7.11 drivers)
Ubuntu Gutsy 7.10 (2.6.22) - no 3D desktop
wine 0.9.51


I am a software engineer and do a little openGL work, starting to do a lot
more and would be interested in looking into assisting with fixing this
problem but have no idea where to start, so if anyone had hints on that
would be good too.
