New status windows - what's this?


I see on the right upper corner of CD:

What is this? What are the functions of this status windows?
how can I remove it?


Go to dragon://flags ; search for “FPS” and disabled the “FPS counter” if enabled and then restart Dragon.

okay, thanks, now can I switch off.
but what’s the point of this feature?
show FPS for a web page that contains text and images?
the fps counter usually is a tool for gamers.
