The following program displays two windows, one parented inside the other.
On our version of X (X11R2), the XMoveWindow causes the interior window
to be painted with a 2 pixel wide border along the upper and left edges.
Pushing and popping the window using uwm causes it to refresh correctly,
with only a 1 pixel border.

Try it with no arguments and one argument, with and without a wm running.
Strangely enough, we see the following behavior:

                      No args     1 arg

        No wm         Fails       Fails

        Modified uwm  Fails       Works

Has this been fixed?  Does this fail on anyone else's systems?
