I'd normally expect that control+L would refresh to repaint that. I
know legacy vi had a behavior similar to this (and correspondingly,
one of the 'cpoptions' that controls a behavior like this). That said,
it's not what most folks want.

Before completely giving up on Exceed/CDE, I'd try poking around to
see if there are terminal emulator options that might align things so
they work. My first guess would be that Exceed's terminal (or
is it HP's terminal) doesn't fully support $TERM=xterm despite
claiming to. So you might try

lowell@linuxbox> export TERM=vt100
lowell@linuxbox> vim myfile.txt

or

lowell@hpbox> export TERM=vt100
lowell@hpbox> ssh linuxbox
lowell@linuxbox> echo $TERM # ensure it's still vt100 not xterm
vt100
lowell@linuxbox> vim myfile.txt

and then perform your tests. It may help to inform Vim that your
terminal isn't as smart as your terminal thinks it is. It may limit
some things like the range of available colors or the use of the
alternate/backing screen (":help xterm-screens") that an xterm
provides, but it hopefully will prevent the redraw artifacts you're
seeing.

Also, if you test your Exceed->HP->Linux link with other (n)curses
tools like Midnight Commander or ranger, nano, lynx, alsamixer, etc.
do you see similar artifacts?
