From the chrome bug report
Driver vendor Mesa Driver version 10.1.3
10.1 was released over a year ago. A lot of bugs have been fixed since then. Can you try a more recent version? 10.5.1 was released recently.
To be brutally honest, I'm not sure. 14.04 is an LTS release that is supposed to be supported for 2 years at least, and possibly 5. And it is using the default driver that Ubuntu makes available, not one of my particular choice. If Ubuntu supplied an update I would pick it up, but I don't normally install my own device drivers.
I see. Well, the way LTS generally works is "if it worked before, it'll keep working, but you get security/etc updates". It didn't work for you before, so that strategy won't work too well for you.
If that is the only choice, I can try to figure it out, but it would be far better if Ubuntu provided updates via the usual distribution path, at least IMHO.
Alternately, if you can point me at a good sent of instructions for how to do this, you could save me some time.
I'm not particularly knowledgeable on Ubuntu. "oibaf ppa" is something I've heard said in connection to Ubuntu and easier availability of pre-packaged mesa. A quick search turns up

which makes claims about supporting Ubuntu 14.04. Hope this helps.
