I set Override software rendering list and Enable WebGL in
chrome://flags but http://get.webgl.org says I don't have WebGL support.
I also tried running chrome with
--disable-gpu-watchdog but it doesn't help. Firefox runs WebGL just fine. I have the same issue with chromium-browser package (39.0.2171.65 Ubuntu 14.10) and also with Chrome (39.0.2171.71).
