Comment 2 for bug 662071

I am experiencing the same bug in Kubuntu 10.10 (regression from 10.04). Since it might depend on the video driver, let me add that I am using a Lenovo X200 Tablet with intel graphics. lspci reports

00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) (prog-if 00 [VGA controller])

Also, while firefox is the application that most readily exhibits the bug, I have noticed similar glitches in a few other applications (e.g. kile) since upgrading to 10.10.
