well I still have this problem in KDE 4.2.3 (kubuntu jaunty + ppa)

run "top" in a konsole and
just open the kmail editor and start typing in the middle of a long line:
"top" reports that xorg uses 80% of CPU !
(yes I mean xorg, not kmail itself)
of course it soon becomes very slow and often continue typing a couple a
seconds after your fingers have stopped...

I must say this is really annoying (especially when you have colleagues peaking
at your screen :( ...)

To compare, doing the same typing in an emacs window makes xorg use about
15%CPU...

In have the feeling that the problem gets even worse when I connect an external
monitor to my laptop (a Dell using intel graphics)
