Uhmm, I am not sure how to interpret these results (All shells or
terminals have been tested with Ubuntu 17.04):

gnome-terminal + bash: Happens
gnome-terminal + zsh: This bug also happens here, lines are getting
removed/repeated...
gnome-terminal + dash: Does not happen. (I changed the
PS1="address@hidden $" to make it longer)
gnome-terminal + mksh: The bug also occured here. Same as bash and zsh.

konsole + bash: Doesn't happen here. I guess this is because konsole
doesn't do text wrapping (The prompt wraps though but not the output
alone.)
