Comment 26 for bug 351186

KDE Windows with effect extremely slow. Creation of new window, moving windows or resizing are all affected.
I believe it is related to ATI card, I am using a Mobility Radeon 3650.

I notice on my monitor that both Xorg and plasma are taking most of my computer resources even when no activity takes place: On the average I would say that palsma takes about 50% of CPU and Xorg about 10%. This is on an Intel Core2 Duo CPU's computer. My screen resolution is 1920x1200.

I upgraded from Kubuntu 8.10 (completely up-to-date) to Kubuntu 9.04 on the day of the official release, using the alternate disk image for the upgrade. About half the upgrade was taken from the CD I burnt, the last half straight from the repository. That happened following a restart of the upgrade process.

I had no speed problems with 8.10. With 9.04 it takes up to 5 seconds to maximise, or minimise) a window, and about 2-3 seconds to create one.

Here are some relevant details. Let me know if anything else may be useful.
