unity 4.5 screen issue

I updated the Unity (to 4.5) because of a unity crash on android OS 4.2.2.

But after update , viewport rect setting is stranged.

There are strange rendering on left and right off set.
(must be black space)

using plug-in

  • 2d toolkit with none tk2d camera.
  • Android Native.
