dmesg output

Using Firefox with the Cairo backend and nouveau drivers sometimes produces incorrect backgrounds. This does not happen on many websites, but if it happens it is always reproducible.

Switching to Firefox without cairo, or using the nVidia proprietary drivers 'solves' the problem. 

This is all on ArchLinux, with nouveau 8.0.3.
