title: How do I stop my VIM background from being transparent in tmux where there is no text?
body: <p>I've been working on moving my development setup to a new Ubuntu based partition from Mac OS.</p>
  
  <p>I'm currently having trouble getting the background to stay solid inside of tmux. </p>
  
  <p>I have TERM set to xterm-256color in my .bashrc and vim works as intended outside of tmux. I have also aliased tmux to "tmux -2" and added</p>
  
  <pre><code>set -g default-terminal "screen-256color"
  </code></pre>
  
  <p>to my .tmux.conf.</p>
  
  <p>My .vimrc contains:</p>
  
  <pre><code>set t_Co=256
  set background=dark
  color Tomorrow-Night
  </code></pre>
  
  <p>I suppose the best way to explain this is with images... Here is the intended look outside of tmux
  (Tomorrow-Night colorscheme):</p>

  <p>And here is what I am experiencing inside of tmux:</p>

  <p>As you can see, the terminal background is bleeding through where there is no text.</p>
  
  <p>Thanks!</p>
