It's pretty dependent on the 2d acceleration provided by your video
driver. For me it's much smoother with the nouveau drivers than the
proprietary nvidia driver, due to the superior 2D. Nvidia drivers
before the 180 series are likely to be particularly bad at this.
Not only is it shiny, sugary UI, I also find it somewhat useful when
browsing to see the various album covers flowing past.

Works beautifully with Jaunty 64 bit proprietary Nvidia drivers 180.22. I notice
minimal CPU usage
if any. Very nice feature.
