Thanks for great work. But in VIM(24bit color version by Zyx_I(https://bitbucket.org/ZyX_I/vim/commits/branch/24-bit-xterm, built with instructions( https://www.reddit.com/r/vim/comments/2ozwe4/24_bit_vim_in_osx_iterm2_a_reality/ ) ), there is a 'Backround-Color-Erasing' problem. Every color is shown well except vim background. Without tmux, everything includes background color works very well.

My environments are vim (built with +termtruecolor told above), tmux, iTerm2-nightly(support 24bit colors) and OSX yosemite.
'set -g default-terminal "screen-256color"' was done in tmux.conf, so echo $TERM ouput is 'screen-256color'. And with no tmux, of course the iTerm profile's 'echo $TERM' output is 'xterm-256color.'
I did 'set t_ut=' prescription(from http://sunaku.github.io/vim-256color-bce.html), but nothing changes.

Are there more settings needed? or Is this an already-known issue of current patch?

@utylee, I got totally same problem. All works great except vim background erasing problem under tmux.

urxvt, tmux, vim, all works good, before 24 bit patch on them.

Did you get any solution? or any guys know?

A modified tip from: https://gist.github.com/choppsv1/dd00858d4f7f356ce2cf

If you want to get this running with homebrew on OS X asap, then just do brew edit tmux and add this paragraph just before the line saying def install:

  option "with-truecolor", "Build with truecolor patch enabled"
  patch do
    url "https://gist.githubusercontent.com/zchee/9f6f2ca17acf49e04088/raw/0c9bf0d84e69cb49b5e59950dd6dde6ca265f9a1/tmux-truecolor.diff"
    sha1 "8e91ab1c076899feba1340854e96594aafee55de"
  end if build.with? "truecolor"

And install tmux with: brew install --HEAD --with-truecolor tmux
