Cinemachine freelook cam jitters in FixedUpdate

Unity Engine
1

I have a new scene setup with a freelook camera. I am testing with low framerate (<40). The update method and blend method is set to FixedUpdate. With all these default settings, the freelook jitters when moves diagonally. Please see the attached video. 8vrm0g
There’s no jitter when moved in one axis only.
If you’re suggesting changing the update method to SmartUpdate, then I have been down that path and it is frustrating as the cam jitters on random occasions like for example when switching to a different vcam with group composer. At least with fixed update this is the only time it jitters.

I am kind of stuck here with this jitter problem as camera is a basic thing to begin with making any game. Even the cinemachine samples seem to jitter. What am I doing wrong?

Do you still have the jitter when you close the inspector?
There is a known issue in Unity Editor that a visible Transform inspector can cause the game view to stutter.
As a general rule, performance tests should always e carried out in a build, never in the editor.
