This should be the good way to achieve the task, using coroutine, without any memory issue:

private Coroutine co_HideCursor;

void Update()
{
    if (Input.GetAxis("Mouse X") == 0 && (Input.GetAxis("Mouse Y") == 0))
    {
        if (co_HideCursor == null)
        {
            co_HideCursor = StartCoroutine(HideCursor());
        }
    }
    else
    {
        if (co_HideCursor != null)
        {
            StopCoroutine(co_HideCursor);
            co_HideCursor = null;
            Cursor.visible = true;
        }
    }
}

private IEnumerator HideCursor()
{
    yield return new WaitForSeconds(3);
    Cursor.visible = false;
}
