Details

(Keywords: parity-ie, Whiteboard: [needs-profile]) 

User Agent: Mozilla/5.0 (Windows NT 6.1) AppleWebKit/535.2 (KHTML, like Gecko) Chrome/15.0.874.102 Safari/535.2

Steps to reproduce:

1. Go to www.123got-it.com
2. Click Login


Actual results:

The animation is jerky (on a Core i3 machine + ATI Raedon 5450).
The animation is done by css3 transforms + css3 animations.


Expected results:

The animation is smooth, as can be seen in IE 9.

Further Information
The speed improves a bit if I scale down and scale up the overlaying div via firebug.  Heuristics on Layers?

This is smooth on my laptop. What's your about:config graphics section say?
Pretty chunky here with Mobile Intel(R) 4 Series Express Chipset Family (latest drivers of course) on Win7 x64. Chrome's a bit better, though I wouldn't call it smoothe either. IE9 is reasonably smooth, though things don't render quite the same as the other two.

about:config gfx are all default.
I suppose you meant about:support:

IE9 is super smooth compared to Nightly and Chrome.
forgot to mention conducted on clean profile.
removal of the box-shadow resulted in perceivable speed-up.
Mass bug change to replace various 'parity' whiteboard flags with the new canonical keywords. (See bug 1443764 comment 13.)
