Just a guess, but could you check the program ids for the vertex/pixel shaders in drawPrimitiveDrawStrided?
ie, prgId in http://source.winehq.org/git/?p=wine.git;a=blob;h=be8c038b273f2bffd4cb76ddc31de3b053c2c47b;hb=2136f3271589afca4c78c84fe503c0a83433ed45;f=dlls/wined3d/drawprim.c#l1800 and http://source.winehq.org/git/?p=wine.git;a=blob;h=be8c038b273f2bffd4cb76ddc31de3b053c2c47b;hb=2136f3271589afca4c78c84fe503c0a83433ed45;f=dlls/wined3d/drawprim.c#l1837
