            Bug ID: 63891
           Summary: Individual characters frequently corrupted
           Product: Drivers
           Version: 2.5
    Kernel Version: 3.11.0-12-generic #19-Ubuntu SMP Wed Oct 9 16:20:46
                    UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
          Hardware: x86-64
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - Intel)
          Assignee: intel-gfx-bugs at lists.freedesktop.org

        Regression: No

I recently upgraded from Ubuntu 13.04 to Ubuntu 13.10, which now uses the
3.11.0-12-generic Kernel.

I believe that this kernel update may have provided updates to my video card
drivers that have lead to individual text-characters often being corrupted,
because the issue spans all applications that display text.

To see the issue I'm having, please view this bug report while giving careful
attention to the video that is posted at the top of comment #4:
