As your using hardware acceleration to perform the animation this is unfortunately one of the side effects. It's quite difficult to overcome this as its part of a fundamental way in which Chrome renders text.
You can set the #slidershow-container
to use -webkit-transform: translateZ(0px);
or alternatively add -webkit-backface-visibility: hidden;
to elements that exhibit this jitter. The downside to this is that it will change the way the text looks rendered in.
