As othres says, it seems that current unity does not render pre-edit text.
I create patch to re-render text on pre-edit text changed. https://code.launchpad.net/~cosmos-door/unity/fix-preedit-663776
This patch is working correctly in my environment (Japanese with ibus-anthy). But I didn't test other environment (Chinese/Korean, and ibus-pinyin/ibus-skk...).
If you can build unity from source, please try it.
