[KDE4] 3 sec untill Dashboard come out

I have to wait about 3 seconds after clicking “Show desktop” for Dashboard to come out. It’s independent of turning on/off desktop effects in KDE4. It last 3 seconds even if Desktop effects are turned off.

I’ve got new OpenSuse 11.0 just after installation. I’ve got drivers for my GeForce 6600 installed from the NVidia repository.

It’s really annoying and I can’t work comfortable with it.

Is there any solution for this problem ?
