I want to include an external tikz-file scaled to size with tikzscale via its version of \includegraphics. However, on top of the picture a lot of garbled paths appear:

It looks like \includegraphics tries to guess subpaths (which don´t exist), but somehow prints them. My MWE is:
\documentclass{article}
\usepackage{tikz}
\usepackage{tikzscale}
\graphicspath{{fig/auxiliary/}, {fig/Matlab/}, {fig/Visio/},
{fig/other/}}
\begin{document}
\begin{figure}[tbhp]
\includegraphics{fig/figure1.tikz}
\caption{a}
\end{figure}
\end{document}
The content of windquiver.tikz is:
\begin{tikzpicture}
\draw[->](0,0)--(1,1);
\end{tikzpicture}
1.1*\figureheightlooks to be in error (there should be no*) although I wouldn't expect it to have that effect but without a real example impossible to debug. – David Carlisle Jun 16 '16 at 22:03\graphicspathhidden in the depths of the template. Updated the question - please feel free to edit it to make it useful to others. – Paul Paulsen Jun 20 '16 at 10:26tikzscaleon\includegraphicsis a very bad design: you can't use usualgraphicxkeys (asangle) with a TikZ picture. – Paul Gaborit Jun 20 '16 at 22:59
