Left side button animation flickers

Binary package hint: netbook-launcher

On Karmic, EEE 900 (Intel graphics), the left side category button animation flickers a bit when the mouse leaves or enters the button. It seems like the animation is reset to its starting state for a fraction of a second, just before it finishes. It's not terribly obvious unless comparing with a smooth animation, like the one on the program icons.

I'll see if I can figure out how to record it.
