Prologue :
Ok so i’m working on this site at work, and our creative designers decided it should have a news ticker in Javascipt. A fade-in/out kind of thing.
I used Mootools (of course) to write a simple script for this. And then I noticed something very strange. While in transition, both in Firefox and IE (6 and 7) the text got Garbled and rendered strangely.
Problem :
I then noticed this deal on another websites :

getstisfaction.com
Preview :
I tried to recreate this , and I made it happen only in IE for some reason.
FIX :
All that needs to be done, is to add background color to the absolute positioned elements that get faded in and out…
like so :
.fade_div{
position:absolute;
background-color:#fff;
}
