Many thanks to Fred Heitkamp! Although his suggestion did not work verbatim on my machine, I got the idea and experimented with partial turning off of the acceleration. (I was unaware of these possibilities.)
It turns out that the one and only adjustment I need to do is to add Option "XaaNoOffscreenPixmaps" to my XF86Config file, in the "Device" section. By the way, it turns out that the pixel corruption at the KDE logo does not occur at all with the latest version of Xfree. So as far as my machine (and experience with it) is concerned, the above line is only necessary to avoid pixel clouds when turning on the grid in xfig. I also took a closer look at these pixel clouds. They come in neat parallel horizontal strips, so it looks very much as if something xfig is trying to do would work vertically but not horizontally. I wonder whether this is an issue of my video card, or the driver. Under Windows I never had to turn down the acceleration, even when I run touchy programs like Civilization 3. So I would think, this may be a driver issue.
