I'm using a scale transform, when accelerated using the force3D property the elements are not repainted correct at the end of the animation. I believe this is a chrome/blink bug but I wanted to see if anyone had anything to share on the matter here.
The issue can be see here: http://jsbin.com/qehuna
Using a non-accelerated tween is fine: http://jsbin.com/sureza
Accelerated CSS transitions are fine: http://jsbin.com/fomuno
As a workaround I've discovered that adding a small non-accelerated transform after the main tween removes the elements from a composite layer and triggers a repaint: http://jsbin.com/vezaxa
