I\'m using a very simple fadeIn and fadeOut in Chrome. I just want one text element to fade out and another to fade in. Working example: http://jsfiddle.net/forgetcolor/7eR5Q
If I go ahead and turn off the webkit font smoothing, the dissolve works great:

So apparantly it removes the smoothing during the transition and adds it after causing the "bump"
