Version:           revision 754191 (using KDE Devel)
Installed from:    Compiled sources
Compiler:          gcc (GCC) 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)

When I enter the Dashboard using the "Show Desktop" applet and then leave it using "Hide Dashboard" in the top-right corner, sometimes (i.e. only when the click is done not too far outside, but also not to far within the circle) this grey circle starts flickering as if I would constantly move the mouse out and in (it gets smaller and bigger very fast). As soon as I move the mouse out of this area (so it's either too far outside or too far inside), the flickering stops.

You can get the same effect when the zoom buttons are enabled without going into dashboard mode - it's caused by the way the hover checks work:

If the mouse is on a button, it counts as hovering on the toolbox, and the toolbox expands.

If the mouse is between the buttons, but not on the toolbox itself, it counts as not hovering on the toolbox, and the toolbox contracts.

The problem is that the contraction can move the buttons under the mouse, causing the toolbox to expand again, thereby moving the button out from under the mouse.  The result is repeated expansion and contraction of the toolbox.

nice solution for no flicker, no jerky hurkey jerky jerk in the toolbox; put an invisible item behind all the tools ;)
