I found my new command in kakoune in tmux to split a tmux window will cause the incorrect color output, and I thought it is the tmux split-window issue.
The followings are my experiments:
This is tmux split-window kak (open a new kakoune instance), and the color is correct
And this is tmux split-window kak -c <client> (open to a existing kakoune instance), and the color is incorrect
The incorrect color means doesn’t support true colors, right?
I don’t know whether this issue is caused by tmux or kakoune.
My tmux config, only forcing true colors:
set -g default-terminal "tmux-256color"`
set-option -ga terminal-overrides ",*256col*:Tc"
My kakoune config, only specify colorscheme to palenight:
colorscheme palenight
