Hello 👋
I use fish's vi mode, which changes the cursor based on mode. However inside tmux the cursor is always block-shaped irrespective of mode.

I tried adding
set -as terminal-features ",*:cstyle"
to my tmux.conf, it doesn't help

Show tmux server log please.

This only happens in fish's vi mode, the cursor changes shape correctly in neovim-inside-tmux

This log is truncated before there is any output from fish.

I've attached a log with echo statements when I changed modes
tmux-server-55560.log

There is no evidence of fish attempting to change the cursor in this log, maybe you are missing some bit of configuration when it is running inside tmux?

I start fish from my bashrc (my default shell is bash, to properly read /etc/profile and /etc/profile.d). I don't think it is possible to miss configuration

bashrc:

export GPG_TTY=$(tty)
gpg-connect-agent updatestartuptty /bye >/dev/null

# If not running interactively, don't do anything
[[ $- != *i* ]] && return

alias ls='ls --color=auto'
PS1='[\u@\h \W]\$ '

if [[ $(ps --no-header --pid=$PPID --format=cmd) != "fish" ]] \
    && [ -z "$BASH_EXECUTION_STRING" ] \
    && [[ $- == *i* ]] \
    && command -v fish &> /dev/null
then
    exec fish
fi


I'll ask fish too, thanks for looking into this

I think you will need to ask the fish developers to help figure out why it is not asking tmux to change the cursor.
