WPF Ribbon (C#) and blurry text

[scifiballer24]

I know about the issues regarding WPF and blurry text due to device-independent font rendering, etc. etc. etc...

But building WPF programs in C# has created no problems for me until now. I'm running VS2010 and using the Ribbon library provided by MS to build a ribbon-based application. As long as I'm not using the ribbon in the application, fonts render perfectly fine...

But when I implement the ribbon into the application via XAML, the text in the application immediately turns blurry. What could be causing this?

For anyone reading this, I'd like to add that the problem seems to be rooted within the "RibbonWindow" control. When the "Ribbon" control is implemented inside of a regular "Window" control, there is no font problem.
