Public bug reported:

Since upgrading to saucy I see frequent corruption of text display. This
happens several times an hour. In all cases, the corruption can be
cleard by forcing a re-draw of the text (e.g. by selecting and
unselecting the affected piece of text).

See the attached screenshot for an example which was supposed to read
"other". This is from Firefox, but I have seen the same issue in
Thunderbird.
