Comment #9 on issue 401106 by k...@chromium.org: webgl no longer works
http://code.google.com/p/chromium/issues/detail?id=401106
This looks like a bug in the packaging of chromium-browser. Please
contact the package maintainers; as far as I'm aware, nobody affiliated
with the Chromium project works on that package. If you see the same
problem with the google-chrome package, please reopen.
