Recently I've been having problems with WebGl on Google Chrome which is a bit of a pain as it is one of the requirements for swanky paint so I can no longer even test on my machine without a workaround.
The good news is that there is a workaround, the problem seems to be caused by WebGL sandbox code interacting with some bad GPU drivers (drivers are always bad) but this can be bypassed by starting chrome with --disable-gpu-sandbox as a command line option.
For me this gets WebGL working again, with Intel GPU drivers on my laptop running under linux. So give it a go, hopefully it will fix your chrome too, this is of course something that should be fixed in a future update of chrome.
BTW you have to make sure that you fully shut down chrome before launching it again otherwise it will just open another window. You can tell that you got it working as chrome will complain about it like this.
Also, here are some downloads as I see the last batch ran out and I forgot to post some on the last blog :)
