你好，我遇到了一个奇怪的问题，使用React原生，屏幕是“跳跃”每当我更新的状态，我猜。真的不知道它可以从哪里来，这里是一个快速视频的问题：

编辑：下面是发生这种行为的屏幕的源代码。

const SContainer = styled.View`
  ${({theme}) => css`
    flex: 1;
    align-items: center;
    justify-content: space-between;
    padding-left: ${theme.container.md}px;
    padding-right: ${theme.container.md}px;
    padding-top: 15px;
    padding-bottom: 15px;
  `}
`;

const SInputContainer = styled.View`
  width: 100%;
  margin-top: 30px;
`;

const SCGU = styled.TouchableOpacity`
  flex-direction: row;
  margin-bottom: 30px;
`;

const SignUp = ({navigation}) => {
  const [checked, setChecked] = useState(false);
  const lastnameRef = useRef();
  const [lastname, setLastname] = useState(null);
  const firstnameRef = useRef();
  const [firstname, setFirstname] = useState(null);
  const maileRef = useRef();
  const [mail, setMail] = useState(null);
  const phoneRef = useRef();
  const [phone, setPhone] = useState(null);
  const passwordRef = useRef();
  const [password, setPassword] = useState(null);
  const confirmPasswordRef = useRef();
  const [confirmPassword, setConfirmPassword] = useState(null);
  const disptach = useDispatch();

  const handleSignup = () => {
    disptach(AccountActions.register());
  };
  const handleCGU = () => {
    alert('CGU');
  };

  const handleLastnameChange = text => {
    setLastname(text);
  };

  const handleFirstnameChange = text => {
    setFirstname(text);
  };

  const handleLogin = () => {
    navigation.navigate(SCREEN_NAMES.AUTH.LOGIN);
  };

  useEffect(() => {
    console.log('render');
  }, []);

  return (
    <Screen

          />
        </View>
      </SContainer>
    </Screen>
  );
};

export default SignUp;

是否有人已经遇到过此类问题？
