Playing first person (unity) games on client and camera movement stopping when mouse hits edge of screen

[storycoolbro]

So when playing first person games in full screen on a client I've only noticed this in unity games but also haven't played any other first person games in other game engines nor do I have any installed to check with. the issue is it seems that the games
Cursor.lockState = CursorLockMode.Locked;
is not being applied to the cursor when using the servers mouse on a client preventing the mouse cursor from being locked to the center of the screen when game is in focus. Causing the camera to stop moving when the cursor reaches the edge of the screen. If I use the clients mouse the cursor stays locked to center of screen but not if using the servers mouse. Is this a Unity specific thing or a deskflow related issue?
