# Handout option in Beamer incompatible with \itemize?

I am making a Beamer presentation and want to use the handout option. However, it turns out that when I add [handout] to the document class, the itemize-environment does not work properly and all items are displayed at once, although I specify that they should be revealed pointwise. What is wrong?

Here is my preamble and an example:

\documentclass[handout]{beamer}
\usefonttheme[onlymath]{serif}
\usetheme{CambridgeUS}
\usepackage[french]{babel}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{tipa}
\usepackage{eurosym}
\usepackage{wasysym}
\usepackage{colortbl}
\usepackage{wrapfig}
\usepackage{graphics}
\usepackage{linguex}
\usepackage{cgloss4e}
\usepackage{csquotes}
\usepackage{xspace}
\usepackage{color}
\usepackage{xyling}
\usepackage{setspace}
\usepackage{amsfonts}
\usepackage{phonetic}
\usepackage{multicol}
\usepackage{booktabs}
\usepackage{multirow}
\usepackage[backend=biber, style=authoryear-comp]{biblatex}
\let\eachwordone\itshape

\beamertemplateballitem

\title{XXX}
\subtitle{YYY}
\author{XXX}
\institute{Flafla}
\date{\today}

\newcommand{\textunderscript}[1]{$_{\text{#1}}$}

\begin{document}

\frame{

\begin{itemize}

\item<2-> Blabla

\item<3-> Flafla

\end{itemize}

}

\end{document}

• That's not a bug, it's a feature. – TeXnician Jun 11 '17 at 10:44

The beamer user guide is very clear about that (mode specifications, 9.6.2):

For this reason, if you write \only<3>{Text} and you are in handout mode, the text will be shown on all slides since there is no restriction specified for handouts and since the 3 is the same as beamer:3.

You have to specify the restrictions for the presentation and for the handout. But be aware, that you usually design a presentation without handout. That option is just used to print the handouts and then removed if you give your presentation.

Here's a real MWE "fixing" your problem (workaround around beamer's design):

\documentclass[handout]{beamer}
\usefonttheme[onlymath]{serif}
\usetheme{CambridgeUS}
\usepackage[french]{babel}

\beamertemplateballitem

\title{XXX}
\subtitle{YYY}
