마르코 다니엘 선생이 알려준 임시방편입니다.

Today I found the bug. Until the next update please use the following definition:

\makeatletter

\renewenvironment{mdframed}[1][]{%

\color@begingroup%

\mdfsetup{userdefinedwidth=\linewidth,#1}%

\mdf@hidealllines@check%

\mdf@twoside@checklength%

\let\width\z@%

\let\height\z@%

\mdf@checkntheorem%

\mdf@styledefinition%

\mdf@footnoteinput%

\color{\mdf@fontcolor}%

\ifvmode\nointerlineskip\fi%

\mdf@trivlist{\mdf@skipabove@length}%%

\ifdefempty{\mdf@frametitle}{}{\mdf@@frametitle}%

\mdf@settings%

\mdf@lrbox{\mdf@splitbox@one}%

}%

{\par\unskip%

\ifmdf@footnoteinside%

\def\mdf@reserveda{%

\mdf@footnoteoutput%

\endmdf@lrbox%

\ifdefempty{\mdf@frametitle}{}{\mdf@@frametitle@use}

\detected@mdf@put@frame}%

\else%

\def\mdf@reserveda{%

\endmdf@lrbox%

\ifdefempty{\mdf@frametitle}{}{\mdf@@frametitle@use}

\detected@mdf@put@frame%

\mdf@footnoteoutput%

}%

\fi%

\mdf@reserveda%

\endmdf@trivlist%

\color@endgroup%

\@doendpe%

}

\makeatother

효과있습니다.
