    window.draw(heading);
    window.draw(particle);
    logPosition(particle, positionLog);
    window.draw(positionLog);
    window.draw(ground);
    ImGui::SFML::Render(window);
    window.display();
  }
  ImGui::SFML::Shutdown();
  return 0;
}

在添加 ImGui 之前，程序运行良好并且显示标题。但是，当我运行这段代码时，它会呈现除标题之外的所有内容。

我尝试改变

window.draw(heading)

的位置，在

window.draw(positionLog)

之后移动它但它没有用。
我不知道是什么导致了这个问题。标题只是一个简单的

sf::Text

对象，类似于

positionLog

，即使

positionLog

被渲染。
