What orbital is saying is that there s no way to turn it off b/c the software that you are using is trying to command direct resources of the WDDM model that is currently being used by the system to display your theme - thus, it will happen every time you use that particular piece of software.
Actually - there is a way to turn it off - but that entails not using Aero at all...then you won't get the message, obviously.
It's the software's fault, not Windows, and until that software is updated, as long as you use Aero you'll get the message and it will switch.
Of course, it can also *sometimes* be dependent upon your GAs, too...since you haven't updated your system specs we can't know if it / they are contributing to the problem or not....
