This sounds to me like screen is loosing state and not (re)displaying
things properly after some condition.

I would bet another order of magnitude that this is the case if you
visually select something so it's highlighted, change screen (disconnect
/ switch screens), change screen back (reconnect / switch back), and
what was highlighted is now underlined.

This seems to have the same symptoms to me.

You can probably test vim, if not eliminate it from the scenario, by
playing with ANSI control codes at a command line and see if the
symptoms are the same as vim when changing screen (see above).
