Looking at dlls/d3d9/shader.c:

In "IDirect3DPixelShader9Impl
*unsafe_impl_from_IDirect3DPixelShader9(IDirect3DPixelShader9 *iface)" line 312
is:

assert(iface->lpVtbl == &d3d9_pixelshader_vtbl);

simply commenting out this line will allow you to run The Witcher 2 as before
with GLSL disabled. Not a real fix, but I'm not familiar enough with Wine code
to do much else. I was just tired of not being able to test the game at all
with newer Wine builds.
