On my Radoen Mobility 7500 (in Vaio Laptop), all kscreensavers found in the kdeartwork-3.2.0 package which rely upon opengl flicker badly, whereas the equivalent screensavers in the xscreensavers package work perfectly.

they work fine here, so it sounds like it may be a problem with xfree configuration? or possibly a kernel issue. have you tried running them with a 2.4 kernel?
Using the same exact kernel, and the same exact xfree configuration, xscreensaver and all other OpenGL programs I run, work perfectly. It is only kscreensaver which exhibits this behavior. If there were a problem with kernel or xfree configuration, one would expect xscreensaver to exhibit it as well. I can post XFConfig86, if necessary.
Hi, I have a Radeon 9000 Pro, and I am experiencing the same horrible flicker with xscreensavers under KDE. The screen saver I have tested with most is glxgears, but all OpenGL screen savers have this flicker. Some points I have discovered: - If you use ATI's proprietary driver and KDE, there is no flicker - If you use Gnome and XFree's open-source driver, no flicker - If you use KDE and XFree's driver, and you run the stand-alone "glxgears", no flicker. - If, under KDE, you type 'xscreensaver' and do a 'test', no flicker. So, only if you use KDE's own screen saver control (Control Center > Appearance & Themes > Screen Saver) do you get this flicker which suggests a problem with that part of the control center. Why it works better with ATI's own drivers, I don't know, but I can't use ATI's driver because it hangs the system.

Is this bug still open?
*** Bug 63760 has been marked as a duplicate of this bug. ***
This bug is most definitely still a problem for me under KDE 3.3.1.
Better move to http://bugs.kde.org/show_bug.cgi?id=73813 Please put your efforts there.
