I did not check the demo in detail yet, but WebKit is the only browsers that does not render the spinning lines on the tape correctly. http://codepen.io/miukimiu/pen/DkvnA
Side note: I am seeing some incorrect positioning at .5x on some iPhones.
Incorrect tick placement in the hubs is caused by use of unprefixed transform-origin. The jumpiness happens because the keyframes rotate from 0->180deg, rather than 0->360deg. I see jumpiness in Chrome too.

I see jumpiness in Chrome too. Can confirm that it is just a problem of prefixing. However, there is a visual difference that seems to be a precision problem. Is that because of pixel rounding? I am fine with closing this bug in general.
