Is it possible that some windowing libraries are responsible for slow re-drawing. Re-sizing firefox seems slow, but resizing any native kde application is quick. resizing adobe acrobat reader is amazing slow, and moving the window around the screen leaves a tracing streak.

Ah-ha! Now that's some info that might provide a lead.

Are you using KDE as your desktop? If so, it is Qt widget library based. Firefox is GTK+-based, and Acrobat is statically linked to Motif. If you can give more examples, maybe we can confirm this.

Qt/KDE is built with some optional X11 (RENDER?) extensions which don't play nice with non-Qt apps (Xt, Xaw, GTK+, Motif, etc...). Didn't know this was the case on CentOS, or maybe it's some other configuration?

I use GTK+/GNOME (gdm/nautilus/metacity session/file/window manager).
