Hi,

I have this error:

? 

with this code:

% Paràbola amb Focus = (0,0.25) i Directriu (x,-0.25)
\placefigure[here]
[taula:construcció-paràbola-1]
{Paràbola amb directriu $r$ i focus $F$}

  with
  {
   \draw[color=gray] (0,-2pt) -- (0,2pt);
  }
}]
\coordinate (F) at (0,0.25);
\draw[very thick] (-2.2,-0.25) -- (2.2,-0.25) node[right] {$r$};
\draw[color=blue, very thick] plot (\x,{(\x)^2});

\foreach \x in {1,0.5,0.75}
{
   \draw[very thick,color=green, loosely dashed,postaction={decorate}] (\x, -0.25) -- (\x , {(\x)^2});
   \draw[very thick,color=green, loosely dashed,postaction={decorate}] (\x , {(\x)^2}) -- (F);
}
\filldraw[color=red] (F) circle (0.5pt);
\draw (F) node[anchor=north] {$F$};
\stoptikzpicture}}

this happens when I updated to the latest version:
$ sh ./first-setup.sh --context=beta --modules=all --engine=luatex

What happens there?

Thanks,
Xan
