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. ** Attachment added: Download window with missing characters https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1342675/+attachment/4416511/+files/2015-06-17%2008%3A29%3A41_download-window_missing-chars.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1342675 Title: Random characters in screen text suddenly disappear To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1342675/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

just noticed also this question and answers on Ask Ubuntu - http://askubuntu.com/questions/584922/how-do-i-fix-fonts-not-rendering- and-missing-letters seems like the issue is most definitely the version of intel graphics driver ubuntu is using. Some people have fixed this by changing to the pure intel graphics driver. Like others, I noticed that using unity-tweak-tool and changing the text scaling factor from 1.0 to 1.15 together within (in firefox) increasing the font size via ctrl+ mouse scroll up fixed these issues in Unity. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1342675 Title: Random characters in screen text suddenly disappear To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1342675/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Happens to me too. Minutes after booting. I found a workaround though ( so at least the laptop is usable again) install ubuntu-tweak . And use it to make the font smaller. 0.9 restores some of the characters and 0.8 size restores them all.
