Hi @nukeop This may be due to an incompatible tool in your rc files.

You can check whether it’s something in your dotfiles by setting up clean configs: Run echo 'ZDOTDIR=/' > ~/.zshenv This forces Zsh to run with zero configs.

We have a list of incompatible tools here: https://docs.warp.dev/help/known-issues#list-of-incompatible-tools

You can disable parts of your dotfiles just for Warp by using this conditional statement:

# Bash and Zsh
if [[ $TERM_PROGRAM != "WarpTerminal" ]]; then
# > What you want to disable here <
fi

I'm using fish, and looking at the list of incompatible tools, I use none of them. I do use omf (https://github.com/oh-my-fish/oh-my-fish), which on its face looks similar to some of the tools on the list. I expect that list is not exhaustive, so maybe that could be the cause?

@nukeop thanks for your patience, yes that could be the cause as oh-my-fish isn't a supported prompt. https://docs.warp.dev/appearance/prompt#custom-prompt-compatibility-table

Please wrap in this conditional in your config.fish file to disable it just for Warp.

# Fish
if test "$TERM_PROGRAM" != "WarpTerminal"
# > What you want to disable here <
end

I'll work on updating those docs to help make this more clear.

Thanks, not ideal, but at least we got to the bottom of the issue.
