Parallax very sluggish

[mmartins]

Hi Guys,

I’ve made some parallax effect on my page, but when scrolling it is very sluggish when the images that do the effect appear on the window. Chrome timeline says ‘Forced synchronous layout is a possible performance bottleneck’

Thanks a lot!

Your problem is mentioned as well, under the option 1.
Author proceeds then to the better ways to achieve the effect.

Bear in mind that using normal hardware scroll with “jumps” always generates janky movement. Try to debug this dragging the scrollbar itself.

After I read the first article I guess that I also have the option 2 problem because I also use translate3d for manipulate the objects.

What I did not understand is if is there any performance issue on using the position:absolute
