Nope, I don't have any other fancy UI programs running. The only program that comes vaguely close to adding buttons to the title bar is Rainmeter. Note: I do have aero running, but I assume you already know that.

As you can see I'm using an Aero theme. In addition, this only happens when window are transparent
