I'm running a single HD7950. I also have issues with the mouse pointer stuttering. Actually I had it with any driver that came after 13.6 beta2. I do have a main monitor attached with DVI, and a TV with HDMI. What I have found is that I clone the desktop to the TV, the stuttering happens. (the TV does not have to be turned on). When I switch to "extend desktop", the stuttering disappears, and everything works fine. However I'd need the clone mode. :/ Also the magnifier running in the background seems to fix the issue, but then again, it's not a viable solution on the long run either. Anyways, I posted a bug report on AMD's support, hopefully they will find what may cause this for the few of us.
