These are almost certainly application bugs. (Unless it can 
be reproduced with the test programs shipped with GTK+, I'd
be pretty certain of that.)

A typical problem is that an application is using the gdk_rgb_*
functions without doing:

 gtk_widget_push_visual (gdk_rgb_get_visual ())
 gtk_widget_push_colormap (gdk_rgb_get_cmap ())

To make sure that widgets are created with the right Visual and
Colormap. (No longer necessary with GTK+-2.0)

The Xinerama / no-Xinerama difference is most likely just resulting in
a different default visual.
