Hi, I was playing with shadows and antialising and I've found a problem. When I set both stencil_blur(1) and d3d_antialias=9 the stencil shadows dissapear, but this doesn't happen when stencil_blur isn't called. Here are three photos of the case:
With d3d_antialias=9 and stencil_blur not called:

With d3d_antialias=0 and stencil_blur called:

With d3d_antialias=9 and stencil_blur called:

As you can see the shadows dissapear. Why does this happen?
