Well,
this is not really the good way to fix the problem (as the surface isn't 
dirtified)

IDirect3DSurface8Impl_AddDirtyRect is an internal function (as seen in 
d3d8_provate.h declaration) so i cannot see where you have found the msdn 
docs ;)

I think you wanted to fix a crash who happened in some 
IDirect3D*TextureImpl_AddDirty* call no ?

if yes, can you try this patch instead ?
