[Pkg-xfce-devel] Bug#684445: xfce4-terminal: unreliable refresh when scrolling in mosh

[Ove Kåven]

Package: xfce4-terminal
Version: 0.4.8-1+b1
Severity: normal

This problem does not always happen. The most reliable way to
reproduce that I've found is:

- In xfce4-terminal, log into another host using mosh.
- If necessary, use "clear", so that the cursor is not at the bottom
- Choose a moderately-sided directory, and "ls" it a few times,
  until the cursor gets to the bottom and triggers a scroll.
  Ideally, the cursor should reach the bottom simultaneously
  with the need to scroll a few lines (not too many), in order
  for the problem to have a high probability of happening.

Result: the bottom line, or bottom few lines, are not drawn, the
space is simply blank. Temporarily covering the terminal with a
different window in order to force it to redraw fixes it, as does
forcing another scroll by hitting Enter again or something.
But it's annoying and distracting, especially since I also often
see the problem in other situations, such as when I use "less".

This only seems to happen with the combination mosh+xfce4-terminal.
It doesn't happen with regular ssh, and it doesn't happen with
gnome-terminal or xterm. The mosh version is 1.2.2-1.

Using "screen" doesn't change anything (both a mosh in a local screen,
and a remote screen in mosh, shows the problem).

And I don't use compositing, in case it matters.
