           Summary: kde sc 4.5 noticeably slower than before upgrade
           Product: kde
           Version: 4.5
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: joris.bierkens at gmail.com


Version:           4.5 (using KDE 4.5.0) 
OS:                Linux

Since I upgraded my Kubuntu 10.4 to KDE SC 4.5 (with some trouble, see
https://bugs.edge.launchpad.net/kubuntu-ppa/+bug/615902), KDE is noticeably
slower. It's workable but not a step forward, rather a step backwards. Just not
as 'snappy'.

Note: it 'feels' like it has to with the graphics rendering. I should note that
I patched xorg.conf so that KDE 4.4 with desktop effects ran smoothly. See
https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/568988. Perhaps
this causes the slowing down now?

Perhaps related to bug https://bugs.kde.org/show_bug.cgi?id=245806 but in my
case it's not seconds but tenths of seconds.

Reproducible: Didn't try
