Comment 0 for bug 1248248

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

See the attached screenshot for an example. This is from Firefox, but I have seen the same issue in Thunderbird.
