When the screen is splited, the resolution is still correct, as shown by "xdpyinfo". Changing the window manager to metacity using "metacity --replace" will fix the splited screen, and the bug will not occur when using metacity.
This bug will not occur if disable 3D effects.
So this bug is more likely a compiz bug.
