Hi, Looks like it is a problem with "StartPage" and "StopPage" in metapost. I get the same error with any MP graphic using those commands. More minimal example (without simpleslides) as per the wiki: https://wiki.contextgarden.net/Cover_Pages colors > 'rgb' color space is supported colors > 'cmyk' color space is supported fonts > preloading latin modern fonts (second stage) fonts > 'fallback modern-designsize rm 12pt' is loaded metapost > initializing instance 'metafun:1' using format 'metafun' and method 'default' metapost > loading 'metafun' as '/usr/share/texmf/metapost/context/base/mpiv/metafun.mpiv' using method 'default' metapost > initializing number mode 'scaled' input stack overflow mtx-context | fatal error: return code: 256 Commenting out "StartPage" and "StopPage" compiles. mtx-context | current version: 2021.05.09 17:14 This is LuaTeX, Version 1.14.0 Development id: 7438 Adam On Sun, May 9, 2021 at 9:57 PM Adam Reviczky wrote:

Hi,

With the latest luatex change from https://github.com/TeX-Live/luatex/commit/1566b63b338abbe38ed839fac9f2022ebb... (and MKIV 2021-05-09 17:14:00) I get an input stack overflow:

MWE from the documentation: \usemodule[simpleslides][style=Boxed] \setupTitle[title={Title of the presentation},author={Name of authors},date={Date of presentation}] \starttext \placeTitle \SlideTitle{The first slide} Write whatever you want. \SlideTitle{The second slide} Continue writing. \stoptext

Does that mean the simpleslides module has some recursion problems? I have tried a couple of themes but getting the same error.
