           Summary: Konsole redraw takes much to long after several hours of
                    use
           Product: konsole
           Version: 1.4.2
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: konsole-devel kde org
        ReportedBy: r.christian gmx de


Version:           1.4.2 (using KDE KDE 3.3.2)
Installed from:    Gentoo Packages
Compiler:          gcc (GCC) 3.3.5  (Gentoo Linux 3.3.5-r1, ssp-3.3.2-3, pie-8.7.7.1) 
OS:                Linux

I am running KDE 3.3.2 with my PII 400MHz laptop. I do seldomly log out but suspend - so my KDE is no in use for 36 hours.

With the time, konsole gets unuseable. I work with 10 tabs and transparent background, fullscreen, and switching tabs takes more than four seconds. But even closing konsole and restart it, only using two tabs and "standard console" color scheme, it takes more than 2 seconds to switch tabs. Konsole is the only program with this problem. Running xterm is fairly normal. The exciting phenomen: even running konsole from a remote host (i ssh into a server and fire up konsole) does not improve the situation - the remote Konsole is as slow as the local- i have no clue, how to get rid of this problem.
Of course, my machine is not under load and has enough of memory. I assume a problem with the X-Server, but konsole is the only program, shoing this problem. Running a top within konsole results in 100% CPU usage of X (drops down to 20% within a few seconds). I use 
X Window System Version 6.8.2
Release Date: 9 February 2005
X Protocol Version 11, Revision 0, Release 6.8.2
Build Operating System: Linux 2.6.11 i686 [ELF]
Current Operating System: Linux alpha 2.6.11 #16 Wed Apr 6 19:49:32 CEST 2005 i686
Build Date: 15 March 2005

The only way to get the system usable again, is to restart kde (which results in a restart of the X-Server). Any hints, how to track this down?
