Hi,
I just stumbled over the following peculiar problem: When typesetting
the following minimal example,
\documentclass{scrreprt}
\pagestyle{empty}
\begin{document}
\[
\sqrt{\sum_i \Bigg(}
\]
\end{document}
with LuaLaTeX, the square root symbol is typeset above the rest of the
math, with a large black box inside. This is reproducible with all koma
script documentclasses. When switching to "article", using pdfLaTeX, or
replacing \Bigg( by something smaller, the formula is typeset as it
should be.
Can someone reproduce this / tell me what the problem is / tell me how
to fix this?
Regards,
Stefan
PS: For the record:
This is LuaTeX, Version beta-0.70.2-2012062812 (TeX Live 2012)
