添加使用 TikZ 制作的图形时，在某些情况下似乎无法打印图形。对我来说，我目前无法找出导致此问题的确切情况。
作为最小的例子，当我使用pdflatex编译时
\documentclass{scrartcl}
\usepackage[utf8]{inputenc}
\usepackage[ngerman]{babel}
\usepackage{graphicx}
\usepackage{tikz}
\usetikzlibrary{shapes,arrows}
\title{Test}
\begin{document}
\begin{figure}
\centering
\begin{tikzpicture}[activity/.style={line width = 1pt, draw, shape = rectangle, rounded corners, minimum width=2.5cm}]
\node[activity] (master) at (1, 0){master};
\end{tikzpicture}
\caption{Test}
\end{figure}
test
\end{document}
主节点按预期打印，但如果我%在测试前面添加，pdf 就只包含,,。
一个更现实的例子是
\documentclass{scrartcl}
\usepackage[utf8]{inputenc}
\usepackage[ngerman]{babel}
\usepackage{graphicx}
\usepackage{tikz}
\usetikzlibrary{shapes,arrows}
\usetikzlibrary{fit,positioning}
\usetikzlibrary{shapes,arrows}
\tikzstyle{line} = [draw, rounded corners, -latex']
\title{Test}
\begin{document}
\section{Test section}

在图片后添加大量文字（3 段）可解决此问题。日志中有Overfull \vbox (11.0pt too high) has occurred while \output is active [3]，因此，过大的数字可能是警告的原因（什么是未满的水平盒子和垂直盒子以及如何去除它们？）。目前我看到的唯一解决方法是改变图形的位置或添加\newpage，这暂时解决了这个问题，但不能创建好的文档。
这是一个已知问题吗/是否有一些解决方法或方法可以进一步追踪此行为？
