未在UWP中呈现PNG文件时勒死错误

Question

这是XAML：

如上所述，我做了一个新页面。
当它运行时，结果是这样的：


如您所见，取消按钮的png不会呈现。
但是，当我调整窗口大小时，cancel的png成功呈现如下：

与此同时，我发现该错误没有规则，有时它会正确渲染，有时直到我调整窗口大小时才像我上面所说的那样渲染。

这是怎么回事？我几乎疯了，因为我什至不知道是什么诅咒。

Answer 1

我按照@Johnny Westlake所说的做到了，删除了-1比例渲染变换并使用Photoshop翻转图像，然后将其添加到对象中。

完成后，我运行了几次，该错误不再发生。

看来确实是UWP中的错误，而Microsoft直到现在都没有修复它。

首先，最后，感谢@Johnny Westlake的帮助。

谢谢。
