yes - I recall commenting on it a while back, and spending some time
to try to resolve it.  I think it's due to the logic which grabs the
text-cursor (termed the "Caret"), as it's used in fshow_cursor and
fhide_cursor.  If the cursor isn't hidden, then it would leave a more
noticeable trail - it's been a couple of years since I last dug into it.

There's also a problem with repainting if there's a modal window (such as 
Task Manager) obscuring part of vile's window.  I've seen the same sort of
problem with PuTTY.

the problem is in the terminal driver...
