I find it interesting that this works, or doesn't. Based on these "Micro-Version" differences as well as whole version differences. What are the key differences? Is it actually chrome or some other system level difference?

Chrome Version 21.0.1180.79 works for me.

3D transforms is nearly completely dependent on the GPU of your machine. about:gpu in Chrome will give you more information about the differences and capabilities of your machine. In some cases, old drivers are too unstable to support and so they're blacklisted by Chrome.

Gah this helped me a lot, thanks. about:gpu told me my WebGL was disabled in about:flags... which it was. Not sure how that happened as that's been annoying me forever.

hm, so you have to check the GPU via JS to check if the user can handle 3D transforms?

about:gpu is nice. thanks.

The browser does to decide if it's safe to use them. JS should be able to just use feature detection.

Why would you be running Chrome version 20? Just restart your browser.

Had exact same question, why would someone purposely disable/prevent the auto-update mechanism?
