I try to put two images wrapped in the top of the page but in the same line, so I made the following MWE:
\documentclass{article}
\usepackage{wrapfig}
\usepackage{lipsum,tikz}
\usepackage{mwe}
\begin{document}
\begin{wrapfigure}{l}[2cm]{0.3\textwidth}
\vspace{-10pt}
\includegraphics[width=0.23\textwidth]{example-image}
\vspace{-10pt}
\end{wrapfigure}
\begin{wrapfigure}{r}[2cm]{0.3\textwidth}
\vspace{-10pt}
\includegraphics[width=0.23\textwidth]{example-image}
\vspace{-10pt}
\end{wrapfigure}
\lipsum[2-18]
\end{document}
And this code give me the following ugly rendering:

But, mysteriously, when I only use the first or the second wrapfigure environment, the rendering work fine:

The problem only appear when I use it twice in the same time in the same page.
So, how can I put on the top of documenter two wrapfigure at the same page height?

[2cm]wrapfigure’s option. – fauve Dec 13 '17 at 16:36
