Buffer bleeding through run output using Vim 8.0

[jondavidjohn]

Upon attempting to upgrade to Vim 8.0, I'm getting some funky output when running specs via vim-rspec. For reference I'll show you what it looks like for me under 7.4

When I upgrade to Vim 8.0, it looks as if the underlying buffer bleeds through the output before I dismiss it.

Additionally, I show in that demonstration that the same thing does not happen when I manually run rspec via straight shell execution (!)

Additionally, I'm customizing the rspec command like so (not sure if it's related)

let g:rspec_command = ':w | !clear && bin/rspec -I . {spec}'

@jondavidjohn I've tried out that rspec_command running on vim 8 and haven't managed to reproduce those issues.

My vimrc is here: https://github.com/dgmstuart/dotfiles/blob/master/.vimrc
