           Summary: [testcase] High CPU usage of Plasma+X when panel
                    overfills
           Product: plasma
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: panel-devel kde org
        ReportedBy: alchark gmail com


Version:            (using Devel)
Installed from:    Compiled sources
Compiler:          GCC 4.3.1 CFLAGS="-O2 -march=core2 -pipe"
OS:                Linux

When the panel gets filled up with too many tasks/tray items, Plasma+X CPU usage jumps up to about 50% (on my dual-core system, Core2 T7500). Steps to reproduce:

1. Open many windows so that the task manager applet becomes full
2. Open an application that creates a systray icon (e.g. Kopete)

Widgets become somewhat condensed and CPU usage rises. After closing the applications it remains high.
