Short description of error
When you use fly navigationing (shift + f) in camera view (numpad 0) after camera has been parented to any object,
the object that is camera's parent and parent's parent move with the camera.

Exact steps for others to reproduce the error

Open Blender
Parent camera to the default cube
Go to the camera view
Move with the fly navigationing
The cube moves like it would be parented to the camera not vice versa.

@ideasman42 that dates back to the original fly code (which is now in ED_view3d_cameracontrol_update ).
Is this by design?

The fix would be to remove the if (vctrl->root_parent) {} block.
To quickly test it: if (vctrl->root_parent && false) { (line 235 on view3d_camera_control.c)

@jylhis what is your usecase? Why did you parent your camera and to what object?

This is a preference, see:

Prefs -> Interface -> View Manipulation -> Camera Parent Lock

However now we have a section for fly mode options it should really be moved there.

The option to move the parent around applies elsewhere so moving to fly mode doesn't make sense.

Note - the purpose of flying the parent, not the camera - is so you can use fly mode with 'camera-rigs' where the camera is often the child of other controlling objects,

closing.
