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.

Some examples:

text tearing image 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).

Output of 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.

Edit:

Going to chrome://plugins/ at the flash-player section I have to following:

Do you have anything in chrome://flags tweaked, especially relating to rendering/hardware acceleration? You might want to look there, it some of the flags could cause rendering problems. –  Andrew Soutar Jan 8 '13 at 23:31
    
To my knowledge I haven't touched that part. –  bioShark Jan 8 '13 at 23:36

I have the same problems, seems that the new Pepper Flash version included by default with Chrome doesn't play well with AMD cards. I haven't found a good way to solve it yet, but a workaround is to just use the normal flash player included by Ubuntu instead.

To do that, go to chrome://plugins

  • On the right side of the screen, click on "Details" if neccasery.
  • Search for the Adobe Flash Player plugin and disable the PPAPI (pepper) plugin, leaving the other one enabled.
  • Restart the browser to apply the changes.

Thanks for the answer. I have tried with both combinations: PepperFlash disabled and adobe-flashplugin disabled and with Pepper disabled and adobe-flashplugin enabled and the tearing is still there. :( Which one is the "other one" for you? –  bioShark Jan 8 '13 at 22:02
    
The working combination for me is Pepper Flash disabled (Right now version 11.5) and the adobe flash plugin (version 11.2) enabled. Make sure to restart the browser too! –  Gladen Jan 8 '13 at 22:06
    
I've added in my question the plugins I have for adobe flash player –  bioShark Jan 8 '13 at 22:07
    
As my edit demonstrates I have the same combo. I am testing with this link: omgubuntu.co.uk/2013/01/… Try to scroll through it. –  bioShark Jan 8 '13 at 22:09
    
I added a screenshot of my setup. –  Gladen Jan 8 '13 at 22:13
