See bug 695272 for an intermittent failure we've seen on linux. This is also permanently failing on mac.
See http://code.google.com/p/chromium/issues/detail?id=101105 for a possible workaround.
Thanks to Ken at Google.

I'd like to land that now. It's still fixing test failures on the slaves.
We should also bother driver vendors about this.
at this point it looks like this is not needed.
Results on webgl-driver-testing show that this seems really needed for many users on Windows with NVIDIA driver, even though this is somehow not needed on our test slaves.

Please approve for mozilla-central. Needed for WebGL conformance on real-world drivers. Very safe. Only affects WebGL, which is not a priority for the upcoming Android release.
