Hi,<br>
<br>
I just stumbled over the following peculiar problem: When
typesetting the following minimal example,<br>
<meta name="qrichtext" content="1">
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px;
margin-right:0px; -qt-block-indent:0; text-indent:0px;"><!--StartFragment--><br>
\documentclass{scrreprt}</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px;
margin-right:0px; -qt-block-indent:0; text-indent:0px;">\pagestyle{empty}</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px;
margin-right:0px; -qt-block-indent:0; text-indent:0px;">\begin{document}</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px;
margin-right:0px; -qt-block-indent:0; text-indent:0px;">\[</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px;
margin-right:0px; -qt-block-indent:0; text-indent:0px;">
\sqrt{\sum_i \Bigg(}</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px;
margin-right:0px; -qt-block-indent:0; text-indent:0px;">\]</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px;
margin-right:0px; -qt-block-indent:0; text-indent:0px;">\end{document}<!--EndFragment--></p>
<meta http-equiv="Content-Type" content="text/html;
charset=ISO-8859-1">
<style type="text/css">
p, li { white-space: pre-wrap; }
</style><br>
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. <br>
<br>
Can someone reproduce this / tell me what the problem is / tell me
how to fix this?<br>
<br>
Regards,<br>
