Hello.

Since I've upgraded from 2.20.18 version of intel driver page previews in Firefox are rendered improperly (see attached screenshot). Tested versions of intel driver are 2.20.{18,19} and 2.21.{0,2,3}, Firefox's versions are 17.0-19.0. I don't think it is a Firefox issues it is completely gone when downgrading back to 2.20.18.

My system is Gentoo amd64, currently with latest Firefox and intel driver. My current kernel version is 3.8 and it is vanilla. I am using SNA acceleration.
If there is any additional info that would be helpful I am ready to provide it.
