Bug#645641: X.org regression slows down cairo apps to a crawl
Package: xserver-xorg-core
Version: 2:1.11.1.901-1
Severity: important
A recent change in the X server caused a massive performance hit to
programs using cairo (so every GTK program and firefox), when running
with the proprietary nvidia driver. I don't know if nouvau is affected.
See this xorg mailing list bug report for details:

A patch that reportedly works around the issue is provided in this
