Wierd ghosting after build

Hi, I need help ><

My scene works just fine in Unity window but when I build the game, strange ghosting effect occers.
It happens for both web player build and widows build.

I attached the images of the scene working in Unity and after build.

Any suggestions?

The version I’m using is 3.1.0f4.

I fgured out what was wrong.
I have only one camera in the scene and its Clear Flags was set to Depth only.
Adding another camera and set flag to solid color fixed the problem.
