Thanks for giving detailed configurations descriptions.

Can you describe your Linux system more specifically? Which distribution (Ubuntu, or Debian, or Fedora, etc) and specific version (for example, my Ubuntu version is 22.04.4)? cat /etc/os-release may help with this, specifically the VERSION= line.

Also, what is your terminal version: gnome terminal --version

And can you give more details on your terminal settings? What is the output of these commands (the last 2 may not exist on your system): echo $TERM echo $LANG tset -q locale

I have not yet been able to get access to a CentOS system where I can reproduce this behavior.

Your TERM variable suggests to me that you are set up to use tmux or screen. Perhaps the behavior is related to this.

Can you try two things and report back? What happens if you open xterm and then in the shell there, run export TERM=xterm-256color and then run vd there? And what happens if you run gnome-terminal, and in that window, export TERM=gnome-256color, and then run vd there?

[lodagro]

tmux is what i use.

Below is the result of the two experiments (using saul.pw/VisiData v3.0.2).

xterm

export TERM=xterm-256color

gnome-terminal

export TERM=gnome-256color

After upgrading tmux to version 3.4, rendering is ok with visidata 3.0.2. The older tmux version i was using was version 3.1b.

So weird. Glad you got it working though, @lodagro!
