Compile selected lines does not complete some animations

[StruggleTownMayor]

Description

When compiling selected lines, sometimes larger (?) animations using the animate package fail to properly complete; it seems to give up after a certain number of frames.

Steps to reproduce

MWE: this is a .tex file containing most of an animation that produced this issue

\documentclass[a4paper,12pt]{article}

\usepackage[controls,method=widget]{animate}
\usepackage{tikz}
\usepackage{lipsum}
\usepackage{pgfplots}

\begin{document}

\lipsum

\begin{center}
\begin{animateinline}{50}
\multiframe{100}{iF=0+1}{
\begin{tikzpicture}[
    declare function = {f(\x)=(\x<1)*(\x+1) + (\x>=1)*(\x+3);}
]
\coordinate (O) at (0,0);
\pgfmathsetmacro{\xLeft}{0.01*\iF}
\pgfmathsetmacro{\xRight}{2-0.01*\iF}
\pgfmathsetmacro{\yLeft}{f(\xLeft)}
\pgfmathsetmacro{\yRight}{f(\xRight)}
\coordinate (pLeft) at (\xLeft, \yLeft);
\coordinate (pRight) at (\xRight, \yRight);
\draw[thick, blue] (0,1) -- (1,2);
\draw[thick, blue] (1,4) -- (2,5);
\fill[red] (pLeft) circle (0.05);
\fill[red] (pRight) circle (0.05);
\draw[red, dashed] (\xLeft, 0) -- (\xLeft, 5);
\draw[red, dashed] (\xRight, 0) -- (\xRight, 5);
\draw[red, dashed] (0, \yLeft) -- (2, \yLeft);
\draw[red, dashed] (0, \yRight) -- (2, \yRight);
\draw [thick, fill=white, draw=blue] (1,2) circle (0.08);
\draw [thick, fill, blue] (1,4) circle (0.08);
\end{tikzpicture}
}
\end{animateinline}
\end{center}

\lipsum

\end{document}

Compiling the full document produces the expected output + working animation.

Select just the lines between the \lipsum and compile selected, I use \lL

Expected behavior

I'd expect it to compile the working animation and output it to the temporary PDF file.

This does work for "smaller" animations it seems.

Actual behavior

The animation seems to stop compiling after a subset of frames but then it appears to think it's finished. The PDF then fails to load.

Do you use a latexmkrc file?

No

That's very strange, and I can't reproduce it on my end.

When you do :VimtexCompileSelected, it will write the intermediate tex file as FILENAME_vimtex_selected.tex. If you are able to reproduce this, can you inspect the diff between your original MWE and the selected version?

[StruggleTownMayor]

Yep it's producing the file exactly as expected - actually I forgot to mention but what I've been doing is compiling the selected lines anyway, switching to that generated _selected.tex file and then compiling that one directly.... which works, funnily enough.

But it's just strange behaviour...

[lervag]

I very much agree it is strange behaviour, but as I can't reproduce it, it is also very hard to help debug it. :\
