OK, it's more… interesting than I first thought.  I can reproduce it
when setting up a screen session inside tmux and I might need to be
connected to the screen session via mosh.  It doesn't consistently
happen even then.  I first thought it had something to do with my
setting TERM to xterm-256color, but it happens with screen-256color as
well.  I've had the issue appear when switching the TERM variable to
xterm-256color and it didn't go away when I've reverted to
screen-256color.  I've meanwhile confirmed I get the same problem when
I'm running under screen-256color all the way from the first shell.

I can actually provoke this by simply typing in a too long line: when
the last character in the last line gets entered, the terminal opens a
new line below, scrolling the content up one line (and keeping the
status line of the tmux in place on the _real_ last line).  It then
scrolls up another line, repeats the the first character of the prompt
on the original line and appends any further characters entered after
that character.

Achim.
