Bug Description
I installed Ubuntu 13.10 (yesterday) in order to test Xmir and Mir natively (examples-clients). Xmirg worked flawlessly. The only "problem" was the duplicate mouse cursor(s).
But I noticed an abnormally high FPS in some clients demo when I tested Mir natively per these instructions

I recorded the test case using external camera. Apologies for the quality but you will see the values.

I attached an apport.log just for more info if are needed.
I'm not a technical guy and I filled this report prompted by @duflu in IRC #ubuntu-mir
You can read the mini conversation here.

This test had the same results either if X only was running in VT7 (Video) or Xmir.
I hope I helped... in something.
Regards

What kind of monitor are you using? What's the vertical refresh rate?
Also, it is nouveau you're using, with an Nvidia GPU right?
