BLOCK THIS It doesn't work on first launch when you've got acrylic + cleartype. In that scenario it starts by using the solid BG by default. Need to investigate... |

So, what I did was use some trickery with
PushLayerto basically create a layer where the text would be forced to render in grayscale AA. I only enable this layer pushing business when both:This plumbs some information through from the TermControl to the DX Renderer to make this smooth.
Validation Steps Performed
