Beamer presentation WITH NOTES. Warning!! “destination with the same identifier has been already used, duplicate ignored” [duplicate]

Question

This question already has an answer here:

• Beamer presentation with notes: navigation does not work properly and “destination with the same identifier” warnings show up 2 answers

I hope this question is not a duplicate; I have seen people observing this same warning, but in a totally different context, like here and here.

The difference is I do not use hyperref for anything, but this problem shows when I attempt to have notes included in my Beamer presentation.

Notably, this warning didn't show with texlive 2013, I am experiencing it with texlive 2015, as I just upgraded to it.

The warning is the following:

destination with the same identifier (name{Navigation2}) has been already used, duplicate ignored

And here a super simple MWE to reproduce it:

\documentclass{beamer}
\mode<presentation> {
    \usepackage{pgfpages}
    \setbeameroption{show notes on second screen=right}
}

\begin{document}

\begin{frame}
\frametitle{Frame with notes 1}
FIRST FRAME CONTENTS
\note{
    Notes for the first frame here
}
\end{frame}

\begin{frame}
\frametitle{Frame with notes 2}
SECOND FRAME CONTENTS
\note{
    Notes for the second frame here
}
\end{frame}

\end{document}

Has anybody observed this warning in the context of a Beamer presentation when hyperref is not used, but notes need to be shown? Does anybody know how to get rid of it? It appears once per slide, so it is really annoying to see soooo many warnings... Thanks!

Answer 1

Workaround

This will disable hyperref, so just be warned that thinks like the navigation symbols will no longer work:

\documentclass{beamer}
\mode<presentation> {
\usepackage{pgfpages}
\setbeameroption{show notes on second screen=right}
}

\begin{document}
\NoHyper
\begin{frame}
\frametitle{Frame with notes 1}
FIRST FRAME CONTENTS
\note{
Notes for the first frame here
}
\end{frame}

\begin{frame}
\frametitle{Frame with notes 2}
SECOND FRAME CONTENT
\note{
Notes for the second frame here
}
\end{frame}
\endNoHyper
\end{document}
