Created attachment 8775608 [details] Capture d’écran 2016-07-28 à 17.48.23.png Height is normal on my side (FF47 Win 7 x32).
Reproduces in 44, not in 37. The font switched from STIX General to Latin Modern Math. I have Version 1.958 installed from texlive-fontsrecommended 2014.
The font from TeX Live 2014 is rather old and most likely have the wrong font metrics.
This is a bug in Ubuntu, please move discussion there: https://bugs.launchpad.net/ubuntu/+source/lmodern/+bug/1502701 It seems that the latest version still did not take changes from Debian's testing.
