Summary: Text display corruption on opening incsearch bar (CtrI-I)

Initial Comment:
System Details:
---------------
    1) OS:       FreeBSD 6.1 RELEASE
    2) Compiler: gcc (i386-portbld-freebsd)
    3) Motif:    OpenMotif 2.2.3 (FreeBSD Port)
    4) NEdit:    v5.5 (FreeBSD Port)

    Notes: NEdit, Motif built from source.  Rest
            binaries (stock).
======================================================
Problem Description:
--------------------
    On pressing Ctrl-I to bring up the incremental-search bar, the text display becomes such that the topmost visible line of text is repeated for each line, with ugly artifacts in-between lines.  A similar situation arises when scrolling upwards by arrow keys, or bringing up the status-line/incsearch bar/tabs via menu/keyboard actions.  In short, any action which leads to text moving _1_line_down_ causes this problem.  PageUp/PageDown or mouse-scrolling show no problems.  When the display is corrupted, iconifying/deiconifying clears it up.  However, NEdit is unusable as such.
======================================================
Steps taken:
------------
    1) No app-defaults file. (Of course.)
    2) *No* .Xdefaults/.Xresources file
    3) No fancy window tools (xcompmgr and the like).
        Just plain mwm.

The problem still occurs.
======================================================
Other Motif Apps:
-----------------
    Run properly, including Xplore, xmmix, DDD, gVim.
======================================================
Attachments:
------------
    None at present.  I can attach screenshots.
======================================================
Current Progress:
-----------------
    Trying to download and check with an NEdit binary.
