注意：这个问题可以删除。问题是由于使用了包 times
在我的beamer .tex文件中，我有两个帧，我使用tikzpicture环境来制作一些动画。这就是为什么我需要在 premable 中包含 TikZ 库。但是，正因为如此，其他帧中的字体正在发生变化。我想要默认字体并想要那个动画。怎么做？
谢谢。如果你删除代码中标记为“问题部分”的部分，那么打印出来的“Hello”与保留该部分时打印出来的“Hello”会有所不同。

备注：这不是答案，但可能有助于发现问题。（内容太长，无法发表评论）
我发现结果没有什么区别。
如果在文档标题中添加，\listfiles您将在日志文件末尾获得所有已加载包的列表。
也许你有一个修改过的文件或者一些个人配置？
