this thing drives me crazy, and I am unable to find a solution...

I am logging in to a FreeBSD machine via ssh using MobaXterm. Every time I open a text file with vim, it replaces the first character of the file with 'g'. It is not just garbling the display, when I try to quit vim, it warns me that the file has been changed, and after writing the file the 'g' is in there of course.

The only thing I was able to figure out that this only happens when TERM is set to an xterm variant (xterm, xterm-color, etc.). It does not happen when using other editors (nano or vi).

Could anyone suggest a solution or point me to the right direction what should I check or reconfigure?

Update:

The output of :scriptnames

I don't have a .vimrc file in my home directory, the one in /usr/local/etc/vim is the unmodified default file that came with the vim package:

if v:lang =~ "utf8$" || v:lang =~ "UTF-8$"

        set fileencodings=ucs-bom,utf-8,latin1

endif



let g:is_posix = 1

set nocompatible

set bs=indent,eol,start

set history=50

set ruler



if &t_Co > 2 || has("gui_running")

        syntax on

        set hlsearch

endif



if has("autocmd")

        augroup freebsd

        autocmd!

        if $PORTSDIR != ""

                autocmd BufNewFile $PORTSDIR/*/*/Makefile 0r $PORTSDIR/Templates/Makefile

        else

                autocmd BufNewFile /usr/ports/*/*/Makefile 0r /usr/ports/Templates/Makefile

        endif

endif

It happens when opening text or binary files.
The issue seems to be related to MobaXterm however; it happens only when I connect with MobaXterm. Vim works normally when I use putty or the physical console ($TERM is xterm in both cases).

I believe this is a bug, that has recently been fixed. Please update your Vim.

Oh and in case of the mobaxterm, this also seems to be a bug of the mobaxterm

Add this to your ~/.vimrc file:

set background=dark

I meet the same problem.
I don't have the solution to fix it.
But I do have a workaround to avoid it.

You can install 'tmux' and use vim on tmux, the 'g' issue would be gone.
