[wmx] border around transparent aterm

I am trying to use my background for useful dynamically updating
things.  I combine wmx and xnodecor for this purpose.

Analog watch appication (oclock) works fine.  However, I encounter a
problem when trying to run a text-based dynamically updating
application (it outputs two lines with battery status, wireless comms
quality, etc., sleep, and outputs the status again, in a loop).

My .xinitrc is as follows:

#!/bin/sh
xset s off
xsetroot -solid gray
oclock -transparent -geometry +880+0 &
aterm -transparent -geometry 60x3+650+150 +sb -cr gray -pr gray -bd gray -ut -e running_status_display &
xnodecor -w oclock
xnodecor -w running_status_display
exec wmx

Everything is fine, except for the fact that there's a one-pixel black
border around aterm.

Any idea how I could remove that border?  (Or what approach should I
use other than aterm?)
