Arch Linux

Description:

offlineimap -u blinkenlights stopped working some time ago. It only shows one line of output (besides the header and footer). With 6.5.7 it worked for a time, and then I think I performed an ncurses update. Originally, blinkenlights caused considerable flicker when executing, and I have been forced to use the basic UI of offlineimap. See here for my BBS post, with some hopefully demonstrative GIFs:

With 6.6.1 it's marginally better, the header and output text no longer flickers, but only one line of actual output is displayed at a time. I expect to see all lines of output as offlineimap executes.

Here's the output I expect to see in the blinkenlights UI (taken from a run of the basic UI):

Hook stderr:

With blinkenlights, only one line of that output is shown at a time, which is less useful. I prefer blinkenlights to basic (or any other UI I've tried) because the color confers information that is lost in the basic UI.

I'm running offlineimap 6.6.1 on OS X using iTerm2, and the problem does not occur. The problem does occur in iTerm2 when I SSH into my Arch system, so I don't believe it to be terminal related. Both rxvt-unicode-256color and terminology exhibit the same problem on Arch.


Additional info:
* package version: 6.6.1-2
* config and/or trace: attached redacted .offlineimaprc, and a gdb trace (which doesn't look very useful to me)
* running offlineimap in tmux, attaching tmux configuration, but running it outside of tmux exhibits the same behavior


Steps to reproduce:

Run: offlineimap -u blinkenlights
