Those artifacts look like an issue with the sampling. Do you know what type of filter is being used to sample the glyph texture?

I'm seeing this in a WPF window also. When I set the number of MIP levels to 1 this issue goes away, but then I of course have lower-quality text.

WPF and D3DImage use premultiplied alpha. That could be the reason.
