Bug#655589: screen: corrupt display after resuming a session

Thu, 12 Jan 2012 07:51:24 -0800 

Package: screen
Version: 4.0.3-14
Severity: normal

With the attached file mscreen2.log (obtained from Xterm log)
and UTF-8 locales:

1. screen sh -c "cat mscreen2.log; sleep 999"
2. Detach the session.
3. Resume the session.

After (1), I get:

q:Quit  d:Del  u:Undel  s:Save  m:Mail  r:Reply  g:Group  ?:Help
   1 N   Jan 12 [email protected] (  22) mail 1
2 N   Jan 12 [email protected] (  0K) tr:re: CONFIRMATIONNN‏NN‏N‏‏NN‏N‏‏N

After (3), I get:

   1 N   Jan 12 [email protected] (  22) mail 1
2 N   Jan 12 [email protected] (  0K) tr:re: CONFIRMATION

This is different! In particular, the first line has disappeared.

Note: the UTF-8 seems to be valid (iconv doesn't complain).

To try directly with Mutt, see the attached file mscreen2, which
is a mbox file telling what to do.

With Mutt 1.5.21+52 (c26dbc7021f4) (2011-07-01):

1. Start screen and open this mailbox, e.g. with
     screen mutt -R -F /dev/null -f <this_file>
   One gets:

q:Quit  d:Del  u:Undel  s:Save  m:Mail  r:Reply  g:Group  ?:Help
   1 N   Jan 12 [email protected] (   4) mail 1
   2 N   Jan 12 [email protected] (  0K) tr:re: CONFIRMATIONN‏N‏‏N‏‏‏‏

2. Detach the session.

3. Resume the session. One gets only:

   1 N   Jan 12 [email protected] (  11) mail 1
   2 N   Jan 12 [email protected] (  0K) tr:re: CONFIRMATION

4. Type the down arrow key. One gets:
