Subject: Fwd: Tearing on Raring + Intel!?

I'm hoping this is just a bug in the Mir staging PPA. Haven't retested 
vanilla raring yet. All my raring machines have the PPA...

Yes, really. My desktop is tearing. And the reason seems to be:
[     1.804] (**) intel(0): Wait on SwapBuffers? disabled

And I find this unexpected too:
[     1.804] (**) intel(0): Triple buffering? disabled

Is this just a hiccup in the xmir build of xserver-xorg-video-intel? I
don't remember if those options were correctly enabled before I
installed the PPA.

Yep. Confirmed this is just a regression in the Mir PPA version of 
xserver-xorg-video-intel. Can we please remember to fix this? (where do 
I log a bug?). I don't think Mir will be the default system compositor 
by 13.10 and we certainly don't want people to see tearing by default...

The tearing is now fixed in the staging PPA:
xserver-xorg-video-intel  2:2.21.9-0ubuntu1+xmir5862+2~raring1

Just do a system update and log out/in again.

Thanks RAOF.
