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).
