I've got some issues with vim in tmux. It is not drawn correctly. I think that the statusbar introduced by tmux messes with the way vim draws its layout. When I create two windows, open vim in one of them and switch to the other one and then back to vim, I see this:
Also, CtrlP behaves weird. It looks like this when I fire it up:
The VIM statusbar is obviously not drawn in this picture. It should be above the CtrlP menu.
The system with this bad behaviour is a debian installation (actually in a chroot inside archlinux). Here is a bit of info about the system and the vim and tmux versions.
