Ubuntu – Chrome/ium rendering problems with Intel Graphics

google-chromegraphicsintel graphicsvisual-artifacts

This is a kinda weird question I don't know what to file it under but this is the behaviour I observe when I try to access pages like facebook (it happened once with google as well. Happens with tumblr now too).

enter image description here

This is a new thing so I haven't really tried to figure out which pages trigger this, I just switched to firefox which seems to work ok (because I am in the middle of some work that needs to be done without interruptions.

The first time this occured I left the page open and tried to figure out what happened the whole graphics turned off and it went to terminal.

I recently installed a ram dimm (if you think that might be somehow related)

My setup:

       CPU: Intel® Pentium(R) CPU B960 @ 2.20GHz × 2 64bit
       GPU: Intel® Sandybridge Mobile 
       RAM: 7.6G

Thanks in advance!

edit: appears to be happening with bookmark manager as well!

UPDATE As of Jan 30, 2014, the bug seems to be fixed. With the latest drivers from oibaf's PPA, there are no graphic glitches in Chrome.


Are you using oibaf's ppa with latest graphics drivers? Looks like there's a bug introduced in recent Mesa builds:

Bug 73978 - Intel driver breaks hardware accelerated flash on Chrome (supposedly related to Flash plugin but it's unconfirmed yet).

The current workarounds are:

EITHER: disable accelerated compositing for now in Chrome by launching it with the following flag:

google-chrome --disable-accelerated-compositing

Notices:

  1. For some reason disabling Accelerated compositing on all pages in chrome://flags didn't do the trick for me
  2. Make sure you stop all chrome's processes by issuing killall chrome before launching it with the command line flag

OR: revert to older graphics drivers by purging oibaf's PPA: sudo ppa-purge ppa:oibaf/graphics-drivers (install ppa-purge if you don' have it)
