I had to disable sna in 2.16.0 when running compiz or I'd get some
graphics corruption, and the problem seems to still exist in 2.16.901 as
well. Here's a screenshot I just took on the RC with sna enabled:

I'm on a ThinkPad X220 (i5-2540M) running Gentoo with the following:
pixman 0.23.6
mesa 7.11
libdrm 2.4.26
xorg-server 1.10.4

Is there anything I can do to help track this down?

This is the first release candidate in preparation for the upcoming
2.17.0 release. We will appreciate any feedback we can get from
testing of this snapshot.
The basis of this release are to push out a couple of critical stability
fixes for SandyBridge and IvyBridge. There is very little else to see
here. Those 200+ other commits do not exist...
