When this happens, what does it say in the right side of the status
line at the bottom of your screen?

What is your Linux terminal type set to? ("echo $TERM")
In any case, it sounds like the "man" program, or the underlying ncurses
library and/or terminfo database, are sending a sequence of characters
that marks the beginning of a "string-bearing" VT220 escape sequence, but
not sending the string terminator. This might be because of terminal-type
mismatch, faulty terminfo entry, etc, but whatever the cause, you can get
out of the situation (when it happens) with Alt-R (Reset).
The real solution, of course, is to identify and fix the underlying problem.
