OS X Yosemite beta 2 is pretty slow when switching applications

After updating to Beta 2 of Yosemite beta (which is "recommended for all users" they say) I got a nasty behaviour: Switching between applications got REALLY slow ... I had to wait 4-5 seconds looking at the nice color wheel ... unacceptable...

 

Rebooting and not starting any applications also didn't help. I started to look what is already running in my menu-bar and ... I found Parallels Access running and uninstalled it - and after a reboot everything is smooth now.

 

Not sure, if this was the real cause but in my case it helped - and I can enjoy Yosemite now even more :)
