Does the issue still occur if you start Firefox in Safe Mode? http://support.mozilla.com/en-US/kb/Safe+Mode

How about with a new, empty profile? http://support.mozilla.com/en-US/kb/Basic+Troubleshooting#Make_a_new_profile

Can you attach a screenshot of the issue?

In Safemode Hardware Acceleration s disabled, so there you do not see the Issue.
Please post your Graphics Info from "about:support".
Would be nice to know if the Issue is still present on a Nightly Build (http://nightly.mozilla.org/).
