快速破解(你要确保你的标题足够短,不会被徽标隐藏):
\documentclass{beamer}
\usetheme{Madrid}
\title{The Title}
\author{The Author}
\institute{The Institute}
\usepackage{tikz}
\addtobeamertemplate{frametitle}{}{
\begin{tikzpicture}[remember picture,overlay]
\node[anchor=north east] at (current page.north east) {\includegraphics[height=0.6cm]{example-image-a}};
\end{tikzpicture}
}
\begin{document}
\begin{frame}
\maketitle
\end{frame}
\begin{frame}{this}
test
\end{frame}
\end{document}
