------- Additional Comments From the3dfxdude@gmail.com 2006-23-10 11:24 ------- Is this problem apparent on your nvidia card? Warcraft III uses fixed pipeline TCL, and WoW appears to use GL_ARB_vertex_shader. In that try this: Run regedit, browse to HKLM\Software\Wine\OpenGL (You may need to create this key) Create a string called "Disabled Extensions". Set the value to GL_ARB_vertex_program.
See this https://bugs.freedesktop.org/show_bug.cgi?id=8250 Note, I also a have a "problem" with flickering model textures or missing parts in Warcraft III, but I have always thought it was related the mesa driver. If you are seeing it on an nvidia card, then the mesa bug is invalid, and both are probably caused by a wine bug.
