I can reproduce buggy appearance in the following, all running on macOS: * iTerm2 * Terminal * The console of a CentOS 7 VM running in Virtual Box Adapting the original function to work with zsh, # Changes: # \w -> %~ # \[...\] -> %{...%} # \$ -> %# calculate_prompt1() { host="my-linux" git_branch="a very very very very very very very very very very very very very very long prompt" prompt="@$host %~ : %{$(tput bold)$(tput setab 1)$(tput setaf 7)%}${git_branch}%{$(tput sgr0)%}%# " export PS1="$prompt" } I cannot reproduce in any of the three environments listed above.
