Estoy intentando hacer un cartel en Beamer. El relleno para entornos de varias columnas es incorrecto: el lado izquierdo de las múltiples columnas está correctamente alineado, pero el lado derecho agrega relleno adicional. Vea abajo:
Esta preguntaPuede estar relacionado, pero la solución no parece hacer nada útil en este caso. yo también hemiré esta soluciónen vano.Esta preguntaparece relacionado y llega a una respuesta parcial, pero no explica el margen derecho espurio. No es un problema con el relleno derecho dentro de los bloques, ya que el problema ocurre incluso si las columnas simplemente se introducen en el frameentorno.
Aquí un ejemplo reducido.
\documentclass[]{beamer}
% Set up as beamerposter
\usepackage[orientation=landscape,size=A4,debug]{beamerposter}
\usetheme{Singapore4}
% Enable T1 (more modern) fonts
\usepackage[T1]{fontenc}
\usepackage[greek,english]{babel}
\usepackage{textgreek}
\usepackage[utf8]{inputenc}
\usepackage{grffile}
\usepackage{ragged2e}
\usepackage{amsmath,amsthm, amssymb, latexsym}
\title[]{Title}
\author[]{Authors}
\date{}
\institute[]{Institute}
\begin{document}
\setlength\columnsep{0pt}
\begin{frame}{}
\begin{block}{}
I've placed hrules in the columns to show that the spacing error comes from the column environment and not the block environment.\\
\hrulefill
\begin{columns}[T,onlytextwidth]
\begin{column}{.5\textwidth-.5cm}\hrulefill\begin{block}{}\vspace{5em}\end{block}\end{column}
\begin{column}{.5\textwidth-.5cm}\hrulefill\begin{block}{}\end{block}\end{column}
\end{columns}
\end{block}
The problem is not related to Beamer blocks as "naked" columns show the same issue:\\
\hrulefill
\begin{columns}[T,onlytextwidth]
\begin{column}{.5\textwidth-.5cm}\hrulefill\begin{block}{}\end{block}\end{column}
\begin{column}{.5\textwidth-.5cm}\hrulefill\begin{block}{}\end{block}\end{column}
\end{columns}
\end{frame}
\end{document}
Y aquí está el código fuente de mi archivo de estilo.

El comportamiento deseado es que los márgenes izquierdo y derecho de un entorno de varias columnas sean idénticos. ¿Alguna idea?
Un MWE más mínimo: observe lo que sucede cuando \setbeamercolor{block body}{bg=gray,fg=black}se elimina.
