>Description:
On a fresh 6.1-RELEASE install [from the ISO images], xterm's
scrollbar thumb either doesn't display, or flickers badly when
dragged.  Identical misbehavior occurs on on two machines I
tested (different display hardware, very different motherboards).

The problem is not present in 6.0-RELEASE, nor does it manifest
after performing "portupgrade -PPR xterm" on that configuration
(i.e. it doesn't look like xterm itself is what's actually
broken).

For comparison, xman's scrollbars seem to work properly.  The
thumb size oscillated in some other X clients I tried, including
xmore and xmessage [using the -file option], but they weren't
unusable.

Might it be an issue with xorg 6.9.0, since 6.8.2
worked properly, or perhaps in one of the shared libraries?

I tried overriding libXaw.so.8 with libXaw3d.so.8; this didn't
help.
>How-To-Repeat:
I have the following lines in my .Xdefaults:

*Scrollbar.thumb: None
XTerm*scrollBar: true

Open an xterm; fill up the window with stuff; press Enter
slowly, and watch what happens.

Then try dragging the thumb using Button 2.
