I am looking at putting my own klugey hack in to fix this by caching
the previous value of the scrollbar parameters. I'll send it to you
if I get it working, and you can decide if you want to incorporate
or not.

Has anyone else noticed scrollbar flicker with 9term?
I have! ;-)
Yes, the scrollbar gets set on each key stroke. One thing I've been
meaning to do for a while is fix it to only draw it when the scroll
bar _changes_. Things pile up 'though.

I've noticed the flicker. It is only a problem in a new 9term. As the amount
of buffered text grows, the flicker rapidly decreases...
I think somewhat earlier versions of 9term didn't do this, but I never
bothered to complain when it first started happening.

Has anyone else noticed scrollbar flicker with 9term?
I haven't looked at the source yet, but I imagine it arises from the
X server actually painting the scrollbar grey and then white one
time for each keystroke.
I don't want to guess at a solution, other than that it could be done
right in 9term by erasing and redrawing a smaller portion of the
scrollbar.
My own window system avoided this problem by having the server do double
buffering -- it gave everything a very smooth feel.
I find the flicker pretty annoying, actually. I'll see what I can do
to fix it, but I thought I'd look around to see what interest there
was for a solution.
