Window maximize delay in Ubuntu Karmic

Window maximize delay in Ubuntu Karmic

I have tried various Ubuntu versions, Ubuntu Karmic Koala 9.10 x86, Ubuntu 10.04 beta DVD, Ubuntu 9.10 AMD64, Mandriva 2010 x86, also a Fedora version and after installing compiz on all OS's, everything is working normal and smooth, even the compiz effects, cube, water, fire, wobbling windows, etc, except of the Maximize effect, where I get 2seconds+ delay for the effect.
