White vertical line on the Metropolis theme background

Question

I am using Beamer's Metropolis theme which is freely obtained in Overleaf. The problem is that if I add the line

\addtobeamertemplate{background canvas}{\transfade[duration=1]}{}

to obtain effects in the presentation, in the PDF document there is a white line on the left side as you can see in this image

How I can avoid this?

I have used the following code, suggested by @samcarter

\documentclass{beamer} 
\usetheme[background=dark]{metropolis} 
\addtobeamertemplate{background canvas}{\transfade[duration=1]}{} 
\begin{document} 
\begin{frame} abc 
\end{frame} 
\end{document}

But the result is the same

Yes. A thin vertical white line appears, it looks like a small bar. But it should not be there. — G al Cubo, Feb 07 '18 at 19:24
@GalCubo What is the purpose of having \transfade[duration=1] in the background canvas? — samcarter_is_at_topanswers.xyz, Feb 07 '18 at 20:54
@GalCubo Can you add a MWE that reproduces the problem? `\documentclass{beamer}
\usetheme[background=dark]{metropolis} \addtobeamertemplate{background canvas}{\transfade[duration=1]}{}

\begin{document}

\begin{frame} abc \end{frame}

\end{document}` works fine for me. — samcarter_is_at_topanswers.xyz, Feb 07 '18 at 21:06
@samcarter I think you can find an answer here: https://tex.stackexchange.com/questions/22412/beamer-transition-effect. — G al Cubo, Feb 07 '18 at 21:09
@GalCubo I know what the transition effect does :) However I am wondering why you want to add it to the background canvas? — samcarter_is_at_topanswers.xyz, Feb 07 '18 at 21:11
@samcarter Ahhh, I understood your question. Well, I've only done what is said here https://tex.stackexchange.com/questions/130071/how-to-change-global-slide-transition-effect-duration-in-beamer/130074 — G al Cubo, Feb 07 '18 at 21:16
@samcarter The idea is to make the transition effects apply to the entire document. — G al Cubo, Feb 07 '18 at 21:20
@GalCubo How are you compiling? With pdflatex or something else? Which tex distribution do you have? — samcarter_is_at_topanswers.xyz, Feb 07 '18 at 21:30
@samcarter I compile using XeLaTeX to load the sources of the theme. That's what you mean? Use TeXLive 2017. I think it's the most current — G al Cubo, Feb 07 '18 at 21:34
I think I've found the same question here https://tex.stackexchange.com/questions/375065/beamer-global-transition-shifts-slide-content/375111 — G al Cubo, Feb 07 '18 at 21:35
@samcarter The answer is just to type \addtobeamertemplate{background canvas}{}{\transfade [duration=1]}, instead of \addtobeamertemplate{background canvas}{{\transfade[duration=1]}{}. A subtle difference! — G al Cubo, Feb 07 '18 at 22:18
@GalCubo As I wrote in the answer you linked to, this is only a workaround - the real answer is to update your tex distribution. — samcarter_is_at_topanswers.xyz, Feb 07 '18 at 22:29
