I have a problem when using Tmux and Vim. As you can see on the picture when I use nerdtree (or irssi, actually any terminal app), I have these kind of rendering problems.
Every key I type modify the entire terminal rendering.
It's only a graphical bug, but it prevents me from working properly. For example, on the screenshot I submitted, nerdtree is opened.
The rendering issue comes mostly when the lines are too long (wrapping) or when I have to scroll (down or up).
I haven't found a way to solve it. Does anybody has this problem too? I really don't know how to solve this.
Many thanks!
Solution already posted:
tmux set-option -g utf8 off
:set tenc=latin1
or
tmux set-option -g utf8 on
:set tenc=utf8
depending on your terminal configuration.
If this didn't fix anything, try
:set isprint=
which will at least let you work, short of seeing magical graphic characters.
Is this a colour issue? If so these might help you:
export TERM=screen-256color solved my issue. See more in the post.
