Hello,
I was running KDE 4.4.1 with Qt 4.6.1 on my computer and the applications are
not really snappy. Sorry I can't describe it any better. I've tried the Gnome
desktop and here everything seems to work much better (when I click on on the
windows title bar the application immediatly comes to the front, overall
responsiveness seems to be better). It doesn't seem to be a sole problem of
kwin, because for example Amarok using the Gnome desktop with Metacity seems to
be still sluggish.

This is using a R600 AGP card using the latest git snapshots from mesa and
xf86-video-ati. On my notebook with a X1400 it seems to run well.

Please let me know if I can do any performance testing.
