我有一个具有主窗口的 WPF 应用程序。在那我有一个框架，框架内容是一个页面。
现在页面中有 4 个 viewport3D，其中包含 Viewport2DVisual3D 并且我有图像元素。
问题：在某些 PC 上，我的应用程序运行良好，但在某些 PC 上，我的应用程序不渲染 viewport3d 或不渲染框架。不知道，但它在主窗口中没有显示任何内容。
该问题发生在 Acer 笔记本电脑型号上。
渲染：
未渲染：
编辑：当我将框架放在网格中时，再次出现此问题。（我在一个框架中显示此页面，该框架是我窗口的主要内容：当我将框架放置在网格中时，它没有显示对象）似乎这发生在具有共享图形的笔记本电脑上
