In the following MWE, the space after enumerate is not the same when I use overlay specification (too big in this case) or when I use a standard enumerate. This problem seems to appear only if the last item finishes with math mode. Any idea to this strange problem ?

\documentclass[10pt]{beamer}
\usepackage[french]{babel}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}

\usetheme{Madrid}
\setbeamercovered{transparent}

\begin{document}

\begin{frame}
    \begin{enumerate}[<+->]
        \item First item
        \item Second item with math mode :
            $$\forall x,\exists y$$    %% Big space after this
    \end{enumerate}
    After enumerate
\end{frame}

\begin{frame}
    \begin{enumerate}
        \item First item
        \item Second item with math mode :
            $$\forall x,\exists y$$    %% Standard space after this
    \end{enumerate}
    After enumerate
\end{frame}

\end{document}

The underlying problem is the same as in Spacing around gather when math color is given: Colour in math mode influences the spacing. This behaviour is known (documented in the graphics package documentation, footnote 2) but hard to circumvent.

A little improvement could be to use \setbeamercolor{math text}{fg=black}. This will add the additional space to all equations, but at least the spaces will be independent of overlays applied or not and offers a stable base to manually correct the spaces where necessary.

\documentclass[10pt]{beamer}
\usepackage[french]{babel}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}

\usetheme{Madrid}
\setbeamercovered{transparent}
\setbeamercolor{math text}{fg=black} 

\begin{document}

\begin{frame}
    \begin{enumerate}[<+->]%
        \item First item%
        \item Second item with math mode :%
            \[\forall x,\exists y\]%    %% Big space after this
    \end{enumerate}%
    \vspace*{-\baselineskip}
    After enumerate
\end{frame}

\begin{frame}
    \begin{enumerate}
        \item First item
        \item Second item with math mode :
            \[\forall x,\exists y\]    %% Standard space after this
    \end{enumerate}
    \vspace*{-\baselineskip}
    After enumerate
\end{frame}
