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

       product: RV770 [Radeon HD 4870]
       vendor: Hynix Semiconductor (Hyundai Electronics)

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 08 '13 at 23:31
  • To my knowledge I haven't touched that part. – bioShark Jan 08 '13 at 23:36

sorry to pop in on this so late. However I was also encountering the issue today and stumbled upon this. What fixed it for me was going to chrome://flags and enabling "Override software rendering list Mac, Windows, Linux, Chrome OS, Android Overrides the built-in software rendering list and enables GPU-acceleration on unsupported system configurations"

I guess for some reason for me 2D hw accel wasn't working.

Just adding this here in case anyone else ever has this issue.

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 08 '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 08 '13 at 22:06
  • I've added in my question the plugins I have for adobe flash player – bioShark Jan 08 '13 at 22:07
  • As my edit demonstrates I have the same combo. I am testing with this link: http://www.omgubuntu.co.uk/2013/01/cnn-predict-ubuntu-phone-wont-make-inroads Try to scroll through it. – bioShark Jan 08 '13 at 22:09
  • I added a screenshot of my setup. – Gladen Jan 08 '13 at 22:13
  • Hm, in that case, I am not sure, I am sorry.. :/ As far as I know it's a problem with the AMD drivers, but I haven't been able to find a proper fix yet.. – Gladen Jan 08 '13 at 22:17
  • I had to use google translate from Dutch to make sure which one is Enabled and which one Disabled :) only to find out that I had them the other way around. But still, for this particular site the issue is still there. Thanks for your help. I'll leave this question around for a while, maybe somebody has an idea. +1 for the effort mate. – bioShark Jan 08 '13 at 22:24
  • Alright, thanks and good luck! I upvoted your question so hopefully someone else is able to help you further! :) – Gladen Jan 08 '13 at 22:30
  • Now after several restarts I have noticed that the tearing has disappeared. So, thanks again, I'll accept your answer. – bioShark Jan 12 '13 at 16:08
