\textbf{}, \textit{} no funcionan en el proyector

Question

Estoy usando la plantilla IMSAloquioum y la modifiqué un poco a lo siguiente

\documentclass[final]{beamer}
\usepackage[utf8]{inputenc}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{nicematrix}
\usepackage{xcolor}
\usepackage{utopia} %font utopia imported
\usepackage{setspace}  % <---
\setstretch{1.3}

\bibliographystyle{alpha}
\usepackage[absolute,overlay]{textpos}
\usepackage{tikz}
\usepackage{tikz-feynman}
\tikzfeynmanset{vanilla/.style=}
\usetikzlibrary{shapes.geometric, arrows}
\tikzstyle{startstop} = [rectangle, rounded corners, minimum width=3cm, minimum height=0.5cm,text centered, draw=cyan, fill=cyan!20]
\tikzstyle{arrow} = [thick,->,>=stealth]

\usetikzlibrary{positioning}
\usetheme{imsa}
\usecolortheme{imsa}
\usefonttheme[onlymath]{serif}
\usepackage[most]{tcolorbox}
\usepackage{colortbl}
\usepackage{wrapfig}
\usepackage[labelformat=empty]{caption}
\setbeamertemplate{background}
{\includegraphics[width=\paperwidth,height=\paperheight,keepaspectratio]{pointbackground.png}}
%------------------------------------------------------------

%Mergin selection%
\setbeamersize
{
    text margin left=0.7cm,
    text margin right=0.7cm
}
%This block of code defines the information to appear in the
%Title page





\setbeamertemplate{frametitle}{%
  \begin{tcolorbox}[colframe=blue,boxrule=0.5pt,top=0.7mm,bottom=0.7mm,grow to left by=5.8mm, grow to right by=5.9mm, before skip=0.07cm,
  interior style={left color=blue, right color=white}]
    \usebeamerfont{frametitle}\usebeamercolor[fg]{frametitle}\insertframetitle
  \end{tcolorbox}
}
\begin{document}



% Title Page
\frame{
\titlepage
}
\AtBeginSection[]
{
{
\setbeamertemplate{background}
{\includegraphics[width = \the\paperwidth, height = \the\paperheight]{toc.png}}
  \begin{frame}
    \frametitle{Table of Contents}
    \tableofcontents[currentsection]
  \end{frame}
  }
}

\setbeamertemplate{background}
{\includegraphics[width=\paperwidth,height=\paperheight,keepaspectratio]{pointbackground.png}}

\small
\begin{frame}{Cross section}
    
\end{frame}


%Bibilographies
\begin{frame}[allowframebreaks]{Bibilography}
    \bibliography{bibitems}
\end{frame}
\end{document}

pero el problema es que ni la cursiva ni la negrita funcionan. Intenté eliminar utopiae insertar otra familia de fuentes, pero no encontré ayuda. Y en la figura, el título viene, pero Fig X.Xno llega.

Answer 1

El tema imsa intenta usarse \usepackage[T1]{fontenc}en un documento destinado a ser compilado con un motor unicode como xelatex o lualatex (debido al uso delfontspec paquete). Ésta no es una buena idea.Como se dijo antes, debe comunicarse con el autor para solucionar este problema.

Mientras tanto, puedes reemplazar el tema con este código:

% !TeX TS-program = lualatex
\documentclass{beamer}
%\usetheme{imsa}

\usepackage[default]{sourcesanspro}
\newfontfamily\DinFF{DINBold.ttf}
%\usepackage[T1]{fontenc}
\RequirePackage{exscale}
\RequirePackage{ragged2e}
\RequirePackage{changepage}
\RequirePackage{fontspec}
%\usepackage{fontspec}
