Comment 23 for bug 726033

jup the problem happens every time. also if it helps: if I scroll down to about the end of the applications list all icons appear and dissappear again about at the time the bottom-most icon is not visible any more. At this breakdown-point the bottom most icon is also drawn over the area below the scroll-bar, which is not drawn on otherwise.
I would guess the error is somewhere in the scrolling-redraw code
