please attach your .vimrc.  that just looks like the terminal is scrolling back up to the scrollback which is normal.
that file is entirely comments except for:
runtime! debian.vim
if filereadable("/etc/vim/vimrc.local")
  source /etc/vim/vimrc.local
endif

i don't know what that runtime line does.  do you have /etc/vim/vimrc.local ?  if so, what is it ?

This was easily reproducible and it's definitely the scrollback. If I install xterm and do vim in there I can't reproduce it in xterm....so this appears to be some issue in hterm itself.  
that's not really a comparable test. xterm doesn't support scroll back when using alt screen (which vim does).
