Do some profile. Run top or hit CTRL+ESC (sort by CPU). Can you confirm
that only kwin (or kdesktop+X) consume *that* many CPU cycles on a parma-
nent basis? If so, a rotten process must be running, which 'poisons' them.
Kwin is merely used as an underlying service here. I used to have some
similar issues with kpager, I suspect as it is very CPU-hungry. Close con-
stituent components in the desktop and have a system monitor running. It
will be able to indicate what causes the problem.
