Maybe it is the terminal emulator problem? What kind of terminal emulator are you using?

My first suspect would be your display driver.  If it has some
"acceleration" or "optimization" features, disable them and try again.

Looks very much like a mismatched terminfo configuration.

What terminal emulator are you using? What is the value of the TERM
environment variable in that terminal emulator immediately after you
start it?

Are you using any kind of terminal multiplexer (screen, tmux,
something else)? If so, what is the value of the TERM environment
variable once you’ve started that?

You mention using ssh. What is the value of $TERM after you connect?
If using a terminal multiplexer, are you starting ssh from a terminal
multiplexer tab, or starting a terminal multiplexer remotely?

iTerm2 in mac os.
However, in other terminal emulator, this problem still exists

On Mac OS
I use XQuartz's xterm
 $TERM is simply xterm

ssh-ing to netbsd-8
 $TERM is wsvt25

I don’t experience garbled display.

The terminal emulator is iTerm2 and no any other terminal multiplexer were used.

$TERM=xterm-256color

Okay, next step, is the terminfo database in CentOS 6.3 recent enough
that it knows about xterm-256color and has the correct definitions for
it?

Start your terminal emulator, log onto your remote CentOS machine, and
issue the following command:

    $ infocmp -x

What does it say?

Hm, at first glance, your terminfo seems to be sane. Sorry, maybe
someone who knows iTerm2 better can help.

Just to have an additional data point, how does Emacs behave if you
set TERM to xterm?

    $ TERM=xterm emacs

Set $TERM=xterm and the problem exists still.

How to find if these features exist? I don't know any any display driver, sorry.

I don't know either, sorry, not for your type of system.  Maybe
someone else here will chime in.  (Does right-clicking on the desktop
bring a menu with something related to display properties?)

Re: emacs display garbled

[조성빈]

I’m not sure about this, and I’m not an expert, but shouln’t it be in the iTerm settings?

I don't think it's an iTerm problem, I think it's a problem with the
video hardware and its driver, according to what I see in the
screenshots.

Unless someone here could tell you how to access the settings of your
video driver, I think you should find out what driver you have, and
read its documentation.
