How can I get vim to draw lines correctly for remote editing?

I'm attempting to edit files on a remote system. I've ssh'd to the system and I start editing with vim.

However, I notice that all the lines are drawing 2 lines above where they really exist in the file. I assumed this was a problem I could fix by dropping my terminal settings to some开发者_如何学编程thing simpler, but that didn't help.

My TERM variable was set to xterm-color. I set it to vt100, but that didn't fix the line drawing issue. I also noticed that this seems to be specific to vim. emacs doesn't show the problem, and I haven't noticed any odd drawing artifacts in less, more or other paging tools.

Other specifics: I'm ssh-ing into the remote system from a Mac, using the Terminal.app. The remote system is running Ubuntu 9.04.

I'm hoping there is something I just need to set in vim to get it to play nice. If it allows me to keep syntax color highlighting, so much the better.

Zhaojun's suggestion works. Setting TERM=xterm is clearing things up.
