Worked: (optional)
Short description of error
Enabling "Auto-Depth" in Navigation appears to cause 0.5-second delay to all navigation commands (pan, dolly, rotate) in Lookdev, and minor framerate stutters in other viewport modes.
Rendered appears to act similarly to Lookdev, however this is most noticable in Lookdev.
Tried multiple fresh installs, always occurs.
Exact steps for others to reproduce the error
Load default Blender scene
In Preferences, set Auto-Depth on
Switch into Lookdev mode. There will be perceptible delay when clicking MMB to navigate.
Barely perceptible slowdown/stuttering in Rendered and Solid viewmodes.
Seems to increase in severity with complex scenes.

IMHO, it's bug or not...

This has been reported before, see #63026 (Camera lag with Auto Depth turned on), will merge these reports
