Cannot set Cursor.lockState to CursorLockMode.Locked at OnApplicationPause

Unity Engine
1

I want to lock mouse cursor after returning from other application by using alt+tab. Everything work fine when I lock it at OnApplicationFocus. But when I lock it at OnApplicationPause, it doesn’t work.

Code:

void OnApplicationPause(bool pauseStatus)
    {
        if (pauseStatus)
        {
            Cursor.lockState = CursorLockMode.None;
            Cursor.visible = true;
        }
        else
        {
            Cursor.lockState = CursorLockMode.Locked;
            Cursor.visible = false;
        }
        Debug.Log("Pause status: " + pauseStatus + " | Lock state: " + Cursor.lockState + " | Visible: " + Cursor.visible);
    }

Result:
Below is result at start of the game. Everything is corrected.

Below is result when switch to other application by using alt+tab. Everything is corrected.

Below is result when return from other application by using alt+tab. Visible is corrected. But lock state should be Locked.

I am using unity 2017.3.

Tested this. You could try reporting a bug to see if it’s by design or not.
I put this together and it seems to be working.

void OnApplicationPause(bool pauseStatus)
{
   if (pauseStatus)
   {
      Cursor.lockState = CursorLockMode.None;
      Cursor.visible = true;
      outputText.text = "Pause status: " + pauseStatus + " | Lock state: " + Cursor.lockState + " | Visible: " + Cursor.visible;
   }
   else StartCoroutine(DelayCursorLock());
}
IEnumerator DelayCursorLock()
{
   yield return new WaitForEndOfFrame();

   Cursor.lockState = CursorLockMode.Locked;
   Cursor.visible = false;

   outputText.text = "Pause status: " + false + " | Lock state: " + Cursor.lockState + " | Visible: " + Cursor.visible;
}
