Girar o tikzpicture bagunça os cruzamentos

Question

Estou trabalhando em uma imagem usando TikZ e estou usando interseções para desenhar alguns pontos (os $α(t_{j+i}$). Vi que a imagem caberia melhor na página se eu a redimensionasse e girasse 90 graus, e para minha surpresa isso bagunça completamente as interseções. Esta é a saída sem rotações ou escalas:

Isso é o que acontece quando dimensiono a imagem (as interseções estão fora dos pontos correspondentes, mas não muito):

E é isso que acontece quando eu giro: completamente bagunçado.

Parece que o TikZ está aplicando duas vezes a transformação: dimensionar para 0,64 em vez de 0,8 ou girar 180 graus em vez de apenas 90. Aqui está o MWE

Alguém sabe o que pode estar acontecendo?

Answer 1

Parece haver um bug no node atuso de interseções.

Aqui está um exemplo :

\documentclass[varwidth,border=50]{standalone}
\usepackage{tikz}

\usetikzlibrary{intersections}
\begin{document}

\tikzstyle{nodepoint}=[inner sep=1pt, circle, draw, black, fill=black]

\begin{tikzpicture}[rotate = 30, scale=1]
  \node[nodepoint]{};

  \draw[name path=a] (120:1) -- (10:1); 
  \draw[name path=b] (0:0) -- (90:1);

  \node[nodepoint, red, name intersections={of=a and b}] at (intersection-1) {};
  \path[name intersections={of=a and b}] (intersection-1) node[nodepoint, green] {};

\end{tikzpicture}

\end{document}

Portanto, substituí- lo \node at (point)por \path (point) nodeele deve estar ok.

EDITAR:Aqui está o código corrigido:

\end{scope}
