[gen4 sna] Font corruption

[Joseph Maillardet]

I noticed that graphical glitches appeared in the letters on many application (Firefox, Empathy, Evolution, ...). Sometime letter completly disappear. I regulary need to select the text to be able to read it.

I'm using Ubuntu-Gnome with "ppa:gnome3-team/gnome3" PPA.
