hmm, I think we were talking of a different bug ^^
I was talking about the flickering we get when a window is move_resized
(this is a very brief flicker, and is most probably due to a bad refresh of
the window from the WM, the old window's content being drawn on the larger
window).
It's much harder to get this bug now, because I have reduced the number of
resizing to the minimum (that's why this bug is marked as "fixed" for us).

The bug you're talking about is different: it's clearly a miscalculation of
the icons positions when an icon is being removed, and it last few seconds
(the time the icon is decreasing to 0), and under any WM (Compiz included).
Actually this is a known bug (and it probably has its own bug report
already), so sorry I didn't understand correctly :-)

The flickering in Metacity is still a real bug afaik, but then I don't think
it affects KWin, so I'm going to remove them.

> Hello,
>
> I'm part of the Cairo-Dock team. Cairo-Dock is a dock using Cairo/OpenGL
> backend. It needs a composite support and it works almost well with
> Metacity. There is just one problem : some flashes appear (often) and the
> dock is moved quickly when the window used by Cairo-Dock is resized. In fact
> Cairo-Dock resizes its window when the dock is active.

> This bug is much present now because the resizing is more used.
