Firefox CSS Animation Smoothing (sub-pixel smoothing)
I'm creating a CSS keyframe animation to have an element appear as if it is casually/slowly floating around a bit. It's nested in parents, one which uses translateX() to slowly move it left and right, and one which uses translateY() to slowly and independently move it up and down. Chrome and Safari render this perfectly, giving it a gradual swaying movement. It smooths the animation (perhaps using sub-pixel smoothing?) so that everything appears very smooth. Firefox however, animates it pixel by pixel, so rather than smoothly swaying about, you can see it jump at every pixel. View the JSFiddle
