Summary: "Scroll up" screws display

Initial Comment:
When scrolling up one line the display shows the newly appearing line plus the second line repeating for the rest of the window. E.g. a "page up" results in a proper display of the file content again, while "page down" only shows the new content on the bottom properly, while the upper half is still the one line repeated.

Message:
The workaround does not work.
I've typed: bash -c "export XLIB_SKIP_ARGB_VISUALS=1;nedit"
and still have the same problem.

I found a solution: using Nedit 5.5 compiled against motif 2.3 fixes the
problem.
It appears to be an incompatability of openmotif 2.3.0 with motif 2.1.
The version that works fine for me is:

See bugs #1773770, #1710741 and #1458006.
If you set XLIB_SKIP_ARGB_VISUALS to 1, the problem will probably go
away.
Eg: XLIB_SKIP_ARGB_VISUALS=1 nedit

We have a workaround in CVS.
