[kde] Anyway to disable the slide effect for plasma pop-ups?

I there a way to disable the slide effect when you click on stuff like
the K menu and the clock on panels? I find it pretty annoying. I want
the fade effect. It seems when I click on the analog clock on my
desktop, the calender fades-in. When I click on the digital clock on my
bottom panel (where the taskbar is), I get the slide effect. I want the
fade effect for everything.
