Created attachment 8681693 [details] Screenshot (comparing good/bad behavior) [Please see the screenshot for the bug, it's much easier seen than described.] STR - Go to https://de.wikipedia.org/wiki/Beobachter_%28Regelungstechnik%29 - Log in and enable MathML rendering of the formulas - See the math taking way too much space before and after the formula itself (see screenshot) The web console says I'm using the font LatinModernMath-Regular system Used as: "Latin Modern Math" I ran mozregression on this, and it came up with https://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?fromchange=d977d6508ad3138c85a209c6ec61e50dfa51be12&tochange=7b56d6b86d1a92237c0a244054efcff86afb7fb3 as regression range. The most likely candidate is bug 1170782. Please let me know if you need the font or any other system information.
What is your system? Which version of Latin Modern Math do you use?
I'm running OpenSUSE 13.2. The font seems to be the version from TeXLive 2013, which is still used in OpenSUSE 13.2 and (more importantly) Ubuntu 14.04 LTS (though I didn't check if the rendering looks the same in this Ubuntu version; I can check tomorrow if needed.) $> fc-list -v 'LatinModernMath' fullname fontversion file Pattern has 3 elts (size 16) fullname: "LatinModernMath-Regular"(s) file: "/usr/share/fonts/texlive-lm-math/latinmodern-math.otf"(s) fontversion: 128319(i)(s) $> rpm -q -f /usr/share/fonts/texlive-lm-math/latinmodern-math.otf -i Name : texlive-lm-math-fonts Version : 2013.84.1.958svn29044 Release : 16.1.7 Architecture: noarch Install Date: Sa 03 Jan 2015 20:33:13 CET Group : Productivity/Publishing/TeX/Base Size : 733996 License : LPPL-1.0 Signature : RSA/SHA256, Mi 08 Okt 2014 19:25:01 CEST, Key ID b88b2fd43dbdc284 Source RPM : texlive-lm-math-2013.84.1.958svn29044-16.1.7.src.rpm Build Date : Mi 08 Okt 2014 19:20:26 CEST Build Host : cloud129 Relocations : (not relocatable) Packager : http://bugs.opensuse.org Vendor : openSUSE URL : http://www.tug.org/texlive/ Summary : Severed fonts for texlive-lm-math Description : The separated fonts package for texlive-lm-math Distribution: openSUSE 13.2

Thanks, that seems to be a duplicate of bug 1208776. I invite you to install the latest version of Latin Modern Math from the upstream website. For OpenSUSE and Ubuntu, see: https://bugs.launchpad.net/ubuntu/+source/lmodern/+bug/1502701 https://bugzilla.opensuse.org/show_bug.cgi?id=948624 The OpenSUSE maintainer does not seem to have time to upgrade TeXLive for now. I did not see much activity on Ubuntu side but Latin Modern is in a separate lmodern package and the bug is already fixed in Debian testing so I expect that this will arrive soon in Ubuntu. I'm not sure what more can be done, but feel free to "help" the Linux distro maintainers :-)
