I've searched the forum and found the history of the Firefox bug and Firefox has fixed the issue. It seems that Chrome is still having the same issue that Firefox once had with the animation flickering. I tried using x, z, rotationZ, force3d, position:relative, and position:absolute used in other topics with flickering animation, but it is proving to be ineffective.
In this codepen http://codepen.io/GreenSock/pen/AGzci if you change the minimum time of 0.5 to 5 seconds in line 15 to slow down the animation you'll see the flickering in Chrome.
Is there no workaround to this problem and we just need to wait on Chrome to fix this?
