Dear KDE users or better KDE experts, Since an update to the latest KDE update '3.5.4a' I observe a more than nasty system on my laptop but also on my x64 desktop box, both running SuSE 10.1. I have to admit that my KDE or maybe X-server debugging knowledge is rather limited. So, ANY hint to solve my problem is highly appreciated. A short discription: When I work as a normal user, who was already using the PCs before the update without any problem, is opening several windows like firefox, openoffice, konsole, kalc, etc.(kde applications and non-kde applications!) in one desktop the windows begin to flicker and the X-process is consuming the whole CPU power, leading to a blocked system. Sometimes this is stopped without any further intervention. I can stop it by hand when I raise the window by the window bar or by resizing the window. I can start it again when I move the pointer from one window the one other. BUT: this is only related to overlapping windows! So, for daughter windows this is always observed (e.g. a YaST application started by/in the YaST main window). This error does not occur for ROOT (ok, ok I know it is not clever to use X-access for root. But root gets more debugging information for the kde applications) and also not for a user who has never used the system before the update, but his home directory was already established before the update was done. The only thing I can observe is the CPU loading (up to 100%) by the X-process. So the X-server is doing something ? No error message in the /var/log files (messages, kdm.log, Xorg.0.log). The only hint I found is in the .xsession-error file for my error-producing user which bears (maybe) some hints for the experts, but not for me. Here I insert the a first part which I found after a fresh login without any application started. ----> SNIP /etc/X11/xim: Checking wether an input method should be started.
