I know my question might be close to this question, but for me none of the solution fixed the issue completely, although one has improved the situation a bit.
Simply put, I have rendering problems on Chrome on pages what seem to use latest fancy flash and other eye-candy (youtube.com among them) stuff. I am experiencing vertical tearing.
What I have:
OS: Ubuntu 12.04
Video Card: AMD HD4870 (still a beast of a card as it runs most new games on high end on high rezolution)
Video Driver: ATI Catalyst official 12.06 (as my video card is considered legacy nowadays, that's the driver to go. Installing the latest 12.10 driver renders me an error of card not supported).
sudo lshw -c video

I have this issues only since I installed the official AMD drivers. Until then I was using the default mesa drivers, and everything was working as a peach. But then Steam came to Linux, and I just had to jump on it. Now my games run smoothly under Ubuntu with Steam, but I have this tearing issues in Chrome.
Ahh, by the way, on Firefox there are no issues.
From the above mentioned post, I have enabled the "tear free" option, and that seemed to reduce the problem a bit, but still didn't eliminate it.
Any suggestions would be welcomed.
Going to chrome://plugins/ at the flash-player section I have to following:
