Comment 9 for bug 353625

I'm currently using 3.0.14 and I'm seeing it here. (3.0.14+build2+nobinonly-0ubuntu0.9.04.1)

Testing with a new profile is really hard, because the problem seems to be intermittent and not easily reproducible. Closing the browser and starting again fixes the issue, so switching to a new profile would fix it too. And browsing all the time with a new profile is not that convenient... (I do realise that the same problem makes it hard to solve the issue too.)

Somewhere else on the net someone made a guess that using compiz might be an issue -- I see the problem on two different Ubuntu installs, one has compiz but the other does not.
