Answer 1

I've removed the line set termguicolors, but it doesn't work. Setting set notermguicolors instead in the .vimrc works.

Answer 2

Using these two lines in my .tmux.conf worked for me, I'm using Ubuntu 20.04 with Alacritty.

Answer 3

I needed vim to display correctly with tmux in terminal on ubuntu and cygwin/mintty on windows. I got it to work by combining the answers like this.

In .bashrc:

alias tmux="tmux -2"

In .vimrc:

" use 256 colors in terminal
if !has("gui_running")
    set t_Co=256
    set term=screen-256color
endif

" fix cursor display in cygwin
if has("win32unix")
    let &t_ti.="\e[1 q"
    let &t_SI.="\e[5 q"
    let &t_EI.="\e[1 q"
    let &t_te.="\e[0 q"
endif

based on answers from this question, this Vim wiki page and this block cursor question

Answer 6

I am using Ubuntu bionic 18.04.4 LTS and tmux 2.6. I have the same issue and it can be resolved by simply adding this into .bashrc
