Description Jim Meehan 2005-04-17 06:32:35 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.7.6) Gecko/20050317 Firefox/1.0.2

Description of problem:
Having some garbled text problems when running mutt under screen. This is on
a remote FC3 server that lives in a colo facility. When I use right-arrow
or left-arrow to scroll through a list of messages, the mutt status line gets
overwritten, some text lines don't get updated, etc. The problem is especially
bad when viewing my spam/junkmail folder where there are lots of messages with
subject lines in unicode/utf-8, etc.

Hitting ^L to redraw the screen does clear up the problem (mostly).
There are still a few out-of-place characters even after ^L when viewing
my spam folder.

I've tried ssh'ing in from Terminal.app in Mac OS X, and PuTTY in Windows -- problem is the same with both.

If I run mutt by itself, without starting screen first, it seems to be
mostly okay. Still a few rendering problems in my spam folder.

I see there's a bugzilla bug #139294 open for a similar problem, with mutt
running under gnome-terminal. Maybe related?

Version-Release number of selected component (if applicable):
screen-4.0.2-5

How reproducible:
Always

Steps to Reproduce:
1. ssh into FC3 machine
2. start screen
3. start mutt
4. go to a folder with several pages of messages
5. scroll through message listing using right/left arrow keys

Actual Results: mutt status line overwritten, text snippets from other pages of messages not cleared from screen, etc.

Expected Results: message list should be displayed correctly, status line should remain intact

This is a known problem with vte as shipped in FC3, and is the same as bug
#139294.  It's been fixed in Rawhide (and the FC4 Test releases) for a while.

Even with the fixed vte, there are problems if you ssh from FC2 to FC3.  But the
problems with screen, PuTTY, etc., are fixed.

Personally, pushing a fixed vte update out there might be a good idea.  But
that's the package with the problem, not screen.

Comment 2 Petr Rockai 2005-04-27 09:39:42 UTC

Please reopen with the right component if still relevant at all. The above  
scenario works for me without problems, so definitely not screen's fault. I  
suppose John is right here and the problem is (was) with vte...
