Description

3 years ago
User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:32.0) Gecko/20100101 Firefox/32.0 Iceweasel/32.0.3
Build ID: 20140925082140

Steps to reproduce:

I bought a website template using lots of nested divs, and added some ajax + javascript opacity animations.


Actual results:

While the animation is running, the first letter of each line of the page is displayed with a 1px offset. Upon animation completion it jumps 1px to the right, to where it should be.

Minimal example: www.8d.no/reflow.html


Expected results:

No movement should be visible.

I am seeing this on Iceweasel 32.0.2, and have seen it on earlier versions as well.
