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.
Created attachment 568790 [details] [diff] [review] workaround This is similar to http://codereview.chromium.org/8365018/ Tryserver push not ignoring this texture-mips test or assuming it to fail anywhere: https://tbpl.mozilla.org/?tree=Try&rev=33979feed4f6
Comment on attachment 568790 [details] [diff] [review] workaround I'd like to land that now. It's still fixing test failures on the slaves.
We should also bother driver vendors about this.
backed out: https://hg.mozilla.org/integration/mozilla-inbound/rev/7030a479b0e3 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.

Comment on attachment 616552 [details] [diff] [review] updated 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.
