Version: (using KDE 4.0.83)
Compiler: GCC 4.3
Open GL screen savers are displayed on a 1/4 of the screen and are slow when the KWin effects are turned on. The screen savers are okay if I turn off the effects.
I also see this but not all the time. Some times it shows at full screen but about 25% of the time it just appears as 1/4 of the (first) screen. This happens even within the same session. I am using a recent svn version.
AMD64 and nvidia 173.14.09.

I am using Beta 2 and I also have an nVidia card with the latest driver
installed. Could it be an nVidia problem since it's the first time I have
been able to use the openGL screen savers on KDE 4.1?
It's not all the time though, like you pointed out. I had fullscreen one time
(for the first time) today :)

I have the same problem. My system is a Dell XPS M1210 with nVidia graphics card
This doesn't affect *all* the OpenGL screensavers on my machine.
Note that both Particle Fountain & Bitmap Flag use same upper left quarter of screen, but the rest of the screen is black, not white.
This machine is an Intel Core 2 Quad Q6600 (x84_64), with an Nvidia 8600 GTS using the nvidia driver 173.14.12. X.org version 220.127.116.11 (10400090).
Linux 18.104.22.168-0.1-default, KDE 4.1 from Suse rpms.
On a hunch, I took "nvidia-settings -a InitialPixmapPlacement=2 -a GlyphCache=1" out of my ~/.xinitrc, but it didn't have any effect on this bug.
I can confirm that turning off kwin's effects fixes the problem.
After a lot of futzing around, I have determined that this bug is intermittent. There are some combinations of enabled kwin effects (always different) where the screensavers work OK, sometimes.
For example, with nothing but the cover switcher on, and repeatedly testing the Euphoria screensaver, it fails about 25% of the time.
Seems to be bug 165552, which has a patch.
..but the patch seems to be incorrect, by the author's own admission. So you might as well add it as a dupe of this one.
Still seing this on 4.2 Beta 1 running on Kubuntu.. Seems to me that the resource-intensive screensavers are the ones who fail to display properly, and more often then not when the cpu(s) is under load.
Nvidia 8800 gts here, Intel core 2 duo, running 64bit
