Hello there, there were some reports regarding the placement of the limits in integrals a few years ago https://tug.org/pipermail/luatex/2015-March/005076.html. It was with regard to display math and `\limits`. They seem to work fine for me, but I spotted some weird behavior using `\displaylimits` *in in-line math*. In my opinion, the limits of integration are placed way too much on the right. The expected behavior is to have the same placement as with `\nolimits` in in-line math, and as with `\limits` in display math. The problem doesn't occur with XeLaTeX and it seems to be independent of a font. Here is a minimal working example comparing different options: ``` latex %! TeX program = lualatex \documentclass{article} \usepackage{unicode-math} \begin{document} \(\int\limits_a^b f(x)\,\mathrm dx\) \(\int\nolimits_a^b f(x)\,\mathrm dx\) \(\int\displaylimits_a^b f(x)\,\mathrm dx\) \[\int\limits_a^b f(x)\,\mathrm dx\] \[\int\nolimits_a^b f(x)\,\mathrm dx\] \[\int\displaylimits_a^b f(x)\,\mathrm dx\] \end{document} ```` Here, the third line after `\begin{document}` is the faulty one.
