Some KWin effects are affecting software what they not suppose.
Example. Effects "Scale In" and "Sliding popups" are being applied together for KickOff if they both are enabled.
The "Scale in" effect does not have a "Scale out" effect (mayby other bug report for that) so the user likes to use other effects as well to give visual effect like "Fade".
With KDE SC 4.4 (beta2) the "Sliding popups" makes plasma notifications and KickOff look nice. But it does look very weird when the Kickoff gets opened with "Fade", "Scale In" and "Fade" effects, all together, but KickOff gets closed only by "Sliding pop-ups" animation.
I think there should not be possible have the "Scale In" effect applied to the KickOff. "Fade" and "Sliding Popups" animations looks good. The other closing animations like "Explosion" does make KickOff as well look weird. Mayby reason for that is that I do not count KickOff as Application Program/Typical window but just as the menu and it should be more like plasma notifications with extended animations.
