4  Known Issues

4.1 Title Formats

Be aware that not every font supports small caps, so the smallcaps or allsmallcaps options may not work for all fonts. In particular, the Computer Modern sans-serif typeface, which is used by default when Moloch is compiled with pdfLaTeX, does not have a small-caps variant.

Note that title format options allsmallcaps and allcaps do not affect the sizes of numerals, punctuation, and math symbol, and are probably best avoided if your titles contain these characters.

4.2 Interactions with Other Color Themes

Moloch can be used along with any other Beamer color theme, such as crane or seahorse. If you wish to do this, it is usually best to include the Moloch subpackages individually so the Moloch color theme is never loaded. This will prevent conflicts between the Moloch color theme and your preferred theme.

For example, overriding the color theme as follows may not work as expected because `loads the Moloch color theme, which defines a relationship between the frametitle background and the primary palette of the theme. Sinceseahorse` assumes a different relationship between its palettes, the result is a grey, rather than periwinkle, frametitle background.

\usetheme{moloch}
\usecolortheme{seahorse}

The correct colors are chosen if the Moloch outer, inner, and font themes are loaded seperately:

\useoutertheme{moloch}
\useinnertheme{moloch}
\usefonttheme{moloch}
\usecolortheme{seahorse}   % or your preferred color theme

Please note that Moloch may not use all the colors defined in your favourite Beamer color theme. In particular, Moloch does not set a background color for the title; this will cause issues when using color themes like whale which set a white foreground for the title.

4.3 Notes on Second Screen

If you use the [show notes on second screen] option built in to Beamer and compile with XeLaTeX, text on slides following the first section slide may be rendered in white instead of the regular colour. This is due to a bug in Beamer or  itself. You can work around it either by compiling with  or by adding the following code to your preamble to reset the text color on each slide.

\makeatletter
\def\beamer@framenotesbegin{% at beginning of slide
  \usebeamercolor[fg]{normal text}
  \gdef\beamer@noteitems{}%
  \gdef\beamer@notes{}%
}
\makeatother

4.4 Standout Frames with Labels

Because the standout frame option creates a group to restrict the colour change to a single slide, labels defined after calling standout will stay local to the group. In other words, the following may result in a “label undefined” error.

\begin{frame}[standout, label=conclusion]{Conclusion}
  Awesome slide
\end{frame}

To fix this problem, change the order of the keys in the frame.

\begin{frame}[label=conclusion, standout]{Conclusion}
  Awesome slide
\end{frame}

This error can be unwittingly triggered if you export your slides from Emacs Org mode, which automatically adds labels after frame options. Alex Branham offers the following solution for Org mode users, using org-set-property.

* Start of a frame
    :PROPERTIES:
    :BEAMER_opt: label=conclusion,standout
    :END:

4.5 Standout Frames with Pandoc

With Pandoc versions prior to 1.17.2 it was not possible to create standout frames because Pandoc only supported a specific list of frame attributes thus ignoring additional attributes such as .standout.
