Bug#504261: compiz: "Show Desktop" icon takes long to restore windows when Compiz is running!

Package: compiz
Version: 0.7.6-7
Severity: normal

Clicking the Gnome "show desktop" icon, shows the desktop at normal speed but clicking that same icon to
restore windows takes particularly longer with compiz running! I haven't experienced this 
problem in Ubuntu and I have the same hardware as I did when I used Ubuntu except that now I have a faster CPU and
more RAM (Intel Pentium Dual-Core E2180) and my video card is: ATI Radeon X600 Pro.
