Now that one is a hard one to answer.
Is it GTK apps? KDE apps calling GTK apps/dialogs? Switching desktop
spaces or windows?
Those could be caused by dbus troubles or other stuff and they are hard
to track down. Right now, I have a problem with sudo. It works not too
long after start up but afterwards, it stops working. All I can say is,
all these random problems are making me more and more inclined to run
something else other than Ubuntu.
So, where and when do you encounter sluggishness again?
