What were you trying to do?
Scroll text in an xterm
What's wrong:
With a particular configuration of overlapping windows, it
incorrectly draws garbage in scrolled areas which become visible during
scrolling (i.e. when the text was originally painted, the text was not
visible, and as it scrolled, the text became visible.)
Here are the windows involved and their xwininfos:

xwininfo ==> Please select the window about which you
==> would like information by clicking the
==> mouse in that window.

What should have happened:
It should scroll properly.
unfortunately, it's not reproducible upon demand, although I've
seen this on previous occasions. I will try to reproduce it and send
instructions...
Ralph saw what was happening and can confirm I'm not hallucinating....
