我发现和的一些奇怪的行为xwatermark我\refstepcounter无法解释。我创建了一个列表，第一个项目的缩进是正确的，但其他所有项目的缩进都太多了。如果改为\stepcounter使用，它又可以正常工作了。如果xwatermark未加载包也是如此。问题不在于如何修复它，而是为什么会发生这种情况。包不应该以任何方式影响布局。我完全无法理解xwatermark与的连接。\refstepcounter

答案1
问题很微妙。使用xwatermark，也会hyperref加载（实际上我不知道为什么）。由于hyperref重新定义了\refstepcounter，它后面的空格变得很重要，并且不会在换行符处被删除，因为它位于hyperref相对于步进计数器的锚点插入的节点之后。
解决方法：删除有问题的空间。
