A quick question about desktop-image rendering on XFCE4

[Peter N. Spotts]

Folks,

I've noticed that with some computer-generated art, XFCE4 renders as
subtle but discreet bands of color portions of images that KDE or Gnome
show as smooth changes from light to dark. Often this happens in skies,
clouds, or other objects where contrast changes quite a bit over a
fairly short stretch of screen. This even happens with some photos,
where colors in clouds or sunsets look a bit like patchwork rather than
blending smoothly from one tone to another. 

Is this a "dithering" issue (not that I could explain what "dithering"
is)? Or just a difference in the way XFCE4 renders images v. KDE or
Gnome? I'm using SuSE 9.1 on a Toshiba satellite laptop, if that's of
any help. Obviously, this is not a showstopper, but inquiring minds want
to know...

With best regards,

Pete
