SNA-issue-4

I'm seeing various screen corruption issues with latest Intel SNA DDX on my Ivy
Bridge. On the kernel side, I have 3.10.1, and on X server side I have Ubuntu
ppa of xserver-xorg-core 1.13.4~git20130508. 

I'm not sure when exactly it started (could be months ago). Switching to UXA
makes the issue in bug-intel-ddx-4.png go away, and probably in
bug-intel-ddx-3.png, but that one is a bit harder to reproduce. 

I'm using mostly GTK2 clients on LXDE environment, without compositing.
