Text display corrupted since upgrade to saucy

[Valentin Tablan]

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.

Here's another example (also from Firefox).

[penalvch (penalvch)]

Valentin Tablan, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p xserver-xorg-video-intel REPLACE-WITH-BUG-NUMBER

Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful.

Thank you for your understanding.
