           Summary: kde plasma framework completely crashed
           Product: kde
           Version: unspecified
          Platform: openSUSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: dav1dblunk3tt at hotmail.com


Version:           unspecified (using KDE 4.4.4) 
OS:                Linux

I'm not sure exactly what has happened - the panel has gone, the wallpaper has
gone, X is still working, kompz is working when I turn it on (alt-shift-f12)
but nothing else is running.  I can start applications from the command line ok
but the desktop appears absent otherwise.  Strangely whatever happened took out
the printing as well...

It seems to stem from the compositing having a bad day, more than 15 windows
and one that was scrolling with a lot of text seemed to consume most of the
CPU.  I turned off compositing which made things way faster and a minute or so
later the panel blinked on and off a few times, restarted with a different
colour scheme, the wallpeper blinked on and off and then both disappeared.

Reproducible: Sometimes

Steps to Reproduce:
Hard to reproduce but once you get few windows, especially busy konsole ones
and a bit of opengl here and there the compositing tends to fall over after a
few hours and things like this often follow but there is no hard and fast rule.
 KDE 4 is very flaky

Actual Results:  
KDE gets more and more flaky over time and the compositing gets slower and
slower until it is a significant frain on resources then things start crashing

Expected Results:  
kde should be fast and rock solid regardless of the number of windows, how much
text is scrolling and how long the computer has been up.

Text scrolling in konsole should never slow the execution of a program in
konsole but when compositing is on this is a major factor on speed
