Physics in Godot runs at 60FPS, when the rendering (and scene updates) differs of it, this kind of bad-sync issues appear.
The player movement runs with at physics rate (and its camera so), so the effect is like the video.

Possible fix:

• Remove the usage of AnimatableBody3D to sync dynamic bodies, instead, use the StaticBody3D. To sync the player with the body, use the ray cast method (as bevy-explorer does)
