I have this problem on Ubuntu 15.04. I had it on previous versions of Ubuntu as well. I did a clean install of 15.04 so the bug is still present in 15.04 (not a remnant of the earlier versions). See attached screenshot. I've seen the missing characters occur in Nautilus and in the gray bar at the top of windows in Ubuntu (e.g., Firefox, gedit, Libreoffice, file download window). On the bright side, it seems to occur less frequently and less severely on 15.04 than in previous versions.
