If you remember bug 21962 especially its comment #56 ;) then you know this
picture, which striked again in wine-1.3.22-193-g68b15bc:

This time tested on nVidia GT240 1GB v275.09.07

1. I did a regression test between 1.3.22 and 1.3.22-203-gac90c1b:

wined3d: Give GL_ARB_map_buffer_range another try.

Nvidia's 270.xx.yy driver series fix the glMapBuffer alignment
    issues that caused major performance problems. If the user is using
    an older driver we now drop the VBO instead of using doublebuffered
    loading, which means that we fall back to the current behavior
    (no dynamic VBO) as needed. Dynamic VBOs are needed on Nvidia drivers
    for GL_ARB_instanced_arrays.

2. Right now no other bug report suffers from this commit.

3. Revert of this patch on top of 1.3.22-203-gac90c1b makes that problem go
away.
