I don't see the issue, I see that: http://i.imgur.com/wVb6750.jpg Could you attach a screenshot of the rendering issue. In addition, are you able to reproduce the issue with a clean profile? https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles

Hi, here is the image: http://i.imgur.com/0W5FhrU.png After some experiments I found that the issue happens extremely rarely in normal situations. However happens very frequently under GWT debug session. I tried a clean profile (my old one was also an almost clear test profile). Nothing has changed. My guess that the issue happens during very high CPU load. I will investigate further and report any findings. Thanks
