Bug description:
  Since upgrading to saucy, I've had individual characters render
  improperly.  Unfortunately, taking a screenshot clears the corruption.
  Selecting the text, scrolling in the terminal (which I imagine redraws
  anew instead of scrolling a rendered pane), or any number of things
  that would trigger a re-display of a glyph seems to clear it.
  Incidentally I see occasional corrupted glyphs appear in this text
  input box as I type, and they will appear with one keystroke and
  disappear with the next.  I am fairly confident I could reproduce as I
  go.

  I filed this against pango because that's what I think of as
  responsible for this sort of thing.

  Screenshot attached.
