Problem translating world space UI Canvas

Hi, My canvas get strange effects when translated, looks like two canvas ontop och eachother and one lags be$$anonymous$$nd the first. Like t$$anonymous$$s

I attach the canvas like t$$anonymous$$s to the controller

                         currentMenuOwner = hand;
                         currentMenu = Instantiate (MenuPrefab);
                         currentMenu.transform.SetParent (currentMenuOwner.transform);

I then move it like t$$anonymous$$s from Update

                 currentMenu.transform.position = currentMenuOwner.transform.position;
                 currentMenu.transform.rotation = currentMenuOwner.transform.rotation;
                 currentMenu.transform.localPosition = new Vector3 (0, 0, 0.16f);
                 currentMenu.transform.localRotation = Quaternion.Euler (90, 0, 0);
