KDE 3.5.5 or Xorg 7.1 makes desktop really slow

Hello people,

Right now I'm facing this problem with Kubuntu Edgy x86_64 (after the upgrade from Dapper), but I have it also with OpenSuse 10.2 so I'm not posting it at the distro sub-forum. Also both are using the newest Xorg 7.1

The problem is that my desktop and I think my whole system is really slow. When I try to scroll down with Konqueror it takes 5 seconds to scroll 1 page. When I try drag a window it leaves many mirrors as a trail behind and restores after some seconds. This didn't happen when I used distros with older kde and xorg.

I have a decent desktop setup with a fast amd64 processor, 1gb ram and ati x1600 video card.

I'm kinda out of places to search, I tried the changelogs from kde 3.5.2 to 3.5.5 but nothing helpful there.

In KSystemLog I found an error saying:
kdm_greet[4721] Internal error: memory corruption detected
and also Xorg uses 80% of my system resources which it shouldn't(found that on KSysGuard)

Is there any other place I should search for something useful?

Try using a generic video driver.

I found that when I got my ATI Radeon running with OpenGL using the ATI driver my system slowed down enormously.

I'm already using vesa and before the upgrade too on both systems (suse,ubuntu) cause I have a buggy combination for the binary ati driver (64bit + x1X00 radeon + xorg6.9). I'm starting to feel that xorg is causing this cause I found many problems on other forums for 7.1 but I'm lost, totally.
