Now I don't see it, it only happened the first times I ran KDE.
That is the opinion of one person in the KDE list:
Umm, now everything seems OK. Maybe it is a bug on the first times that
KDE
is run?
Not impossible but highly unlikely, My guess is that it is one of those bugs which only happen as a weird sideeffect of something else, e.g. a certain system state. Unfortunately this makes them extremely difficult to debug, since in order to fix a bug one needs to be able to reproduce it relyably.
