When adding a figure made with TikZ, it seems like figures are not printed in some situations. For me, I currently cannot find out which are the exact circumstances causing this issue.
As minimal example, when I use pdflatex to compile
\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}
The master-node gets printed as expected, but if I add % in front of test, the pdf just consists of ,,.
A more real-life example is
\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}

Adding much text (3 paragraphs) after the picture solves this issue. In the log, there is Overfull \vbox (11.0pt too high) has occurred while \output is active [3], therefore, the figure which is too big might be the reason of the warning (What are underfull hboxes and vboxes and how can I get rid of them?). The only fix I currently see is changing the position of the figure or adding \newpage, which solves the issue for now but does not create a nice document.
Is this a known issue / is there some workaround or way I could further trace this behavior?
