So I'm not quite sure if it's a neovim or fzf issue hope you guys can help me on this, I am running into a very annoying issue, for some reason, anytime I run FZF from neovim with let g:fzf_prefer_tmux set as 1 it seems that neovim gets suspended, and blocks all the content of the file opened at the moment, I know it might seems a very silly problem but sometimes I'd like to search something based on an info within the file I'm editing. Here's how it looks like.

this very simple setup is able to reproduce this issue

" init.vim
call plug#begin('~/.vim/plugged')

Plug '/usr/local/opt/fzf'
Plug 'junegunn/fzf.vim'

call plug#end()

let g:fzf_prefer_tmux = 1

NVM: 0.3.4
FZF: 0.17.5
TMUX: 2.8

Thanks in advanvance.

Yeah, it's a known issue on Neovim, but I'm not aware of a way to fix it. You can easily reproduce the case using the following command:

" Hides the upper window if run on Neovim, but not on regular Vim
:call system('echo foo | fzf-tmux')

My money is on tmux being the issue. If I have tmux disabled then run fzf in neovim it runs without a hitch.

This is still an issue. Is this related to how neovim launches fzf through the built in terminal instead of as an external command like in regular vim?
