My 12.04 install sometimes does this to the text on the screen:
This happens on all text in nautilus, all context menus, bookmarks/omnibox/statusbar on Chrome, and elsewhere in other programs. I've never had it happen to me after a clean boot, but it does sometimes happen after I boot from a hibernated OS.
I had recently installed Gnome Shell 3(unstable), but I removed it later, and this problem started then.
How ought I fix this?
