Camera movement when using OnAnimatorIK() -> Jittering.

I have a character whose movement is controlled via IK / OnAnimatorIK().
The character’s movement is perfect - smooth as silk - when viewed in “Scene” window.

However, if I switch to the “Game” tab, I see a lot of “jittering” in the character’s movement. The “in game” camera is moved during Update() to track the character. I modified the code to cause the camera movement to occur in LateUpdate() with no success; the jittering is still there.

In fact, even if the “in game” camera isn’t moved during updates/lateUpdates, I still see some slight jittering in my character’s limbs that isn’t present when viewed in the “Scene” window.

Any ideas on how to get the “in game” camera to work like the “Scene” window’s camera? The “scene” window’s camera is doing something “right” (or at the right time) that the “in game” camera isn’t.

Tried various events for camera update. Nothing works. Jitter and hitches still there. And all the while, the character is moving perfectly in the “Scene” view, smooth as can be. Does sample code exist that shows the proper way to do this? Crazy. Seems like it would (should) be “fall of a log” simple. Something of a show-stopper if it can’t be fixed.

Update: Restarted Unity and the problem, for all intents and purposes, is gone. Still not quite as smooth as it appears in the “scene” view but good enough. Will have to see if it creeps back over time…
