"Flickering" camera bug on each Unity startup

Hello,

I am working on a 2.5D platformer. We are using the DoubleJump Controller found on UnifyWiki and putting all the MouseLook values at 0 to prevent the camera from moving (only following the character on the X and Y axis).

The problem is, our camera is "flickering" (tilting really fast). We found a way to fix that bug by simply removing the DoubleJump Controller script and placing it again unchanged: the camera is then completely stable. But each time we restart Unity or compile the game, the bug is still there.

It's a big problem, since we can't have an .exe or web version of the game without the bug.

I searched for a day on a fix for this and I am completely lost. This seems like an Engine bug since it can be correctly just by deleting and bringing back a script.

What should I do?

(I could upload a video of the bug if it isn't clear)

i have the same problem !!! how can i solve the problem

I had problem with jittering camera due to camera controllers using Update or LateUpdate, using FixedUpdate instead fixed the problem. If you have several cameras in your scene, only one camera should be tagged Main Camera.

Does this only happen with Unity 3? I'm facing a same sort problem that everything is flickering in my third person overview cam if it is moving forward. The problem disappears if everything is standing still. I posted a little example project on the Unity forums. Please take a look if that's the same problem. Flickering Mesh
