Not sure if it's related to vim configuration, tmux settings or ssh config, I opened a file with vim on a remote server, and every time when I use
:vsp command to split a vertical window, the right window sometimes is not rendered correctly, and some lines in right window will go across the borderline to the left window, as shown in the attached picture.
I tried to disable all
/etc/vimrc, it happens the same. No idea how to debug this cause I am not an expert of Vim nor tmux nor ssh.
Could anybody show me some hints of how to debug this?
