Since my last upgrade of Arch Linux (a month ago perhaps), my screen looks weird.

It happens randomly, and it would become normal with a slight update to the current window.

See this screenshot of chromium browser for example,

enter image description here

If I scroll up or do anything that "updates" the browser, it would become normal again.

Was it a problem related to X or the chromium browser? Anyone knows that?

You really should read pacman's output:

grep -A7 SNA /var/log/pacman.log 
[2013-08-26 14:49] [ALPM-SCRIPTLET] >>> This driver now uses SNA as the default acceleration method. You can
[2013-08-26 14:49] [ALPM-SCRIPTLET]     still fall back to UXA if you run into trouble. To do so, save a file
[2013-08-26 14:49] [ALPM-SCRIPTLET]     with the following content as /etc/X11/xorg.conf.d/20-intel.conf :
[2013-08-26 14:49] [ALPM-SCRIPTLET]       Section "Device"
[2013-08-26 14:49] [ALPM-SCRIPTLET]         Identifier  "Intel Graphics"
[2013-08-26 14:49] [ALPM-SCRIPTLET]         Driver      "intel"
[2013-08-26 14:49] [ALPM-SCRIPTLET]         Option      "AccelMethod"  "uxa"
[2013-08-26 14:49] [ALPM-SCRIPTLET]       EndSection

The Arch Wiki Intel page has a little more detail on the move to SNA as the default acceleration method.

Do another pacman -Syu and reboot. In the last month, there have been ATI driver updates, at least 3 kernel updates (even for LTS kernel), and I seem to recall some X11 updates. I know that something in X11 changed, and then changed again, I'm not sure what it's due to.
