I'm a heavy customizer myself so I know the feeling...
Please check the archive for the kde-linux list, where I earlier this
week described the troubleshooting technique known as bisecting, in a
thread entitled "Loosing keyboard in KDE" (yes loosing, someone mixed up
loose and lose).
Very briefly, the idea is to backup your $KDE_HOME dir (~/.kde), then
while not logged into kde as that user, delete roughly half of the
working dir (thus the backup), then login and see if the problem is still
there or not, which tells you whether the problem is in the half you
deleted or the half you didn't. Using that information, you repeat,
splitting the bad half each time, until you find the problem file. If
you wish, you can then switch to a text editor and continue the same
process into the file, until you find the problem section, and then the
problem line. Of course you can stop at any time if you believe the
hassle recustomizing what's left will be less hassle than continuing the
bisect further, but I generally continue it since it's useful to know
what the problem was if it ever happens again.
But to speed up the process, the two main config dirs under $KDE_HOME are
share/apps, which contains application specific subdirs, and share/config,
which contains individual files. So I'd make the assumption it's one of
those, backup and delete the other, and see if that's it, If not, try
the other one.
The other thread has a more detailed description of the bisect method.
But we can probably speed the process even further, as from your
description, the problem is very likely kwin or plasma related. So after
getting your backup, try deleting just the kwin files under both of the
dirs above, and see if that cures the problem. If not, try the plasma
files, but I'm suspecting kwin so try it first.
