Please put me in cc, as I am not subscribed to the list. > If it's the same issue, (changed sunday 6th August) I think it was a change in gsettings...something - it only bothered me using chromium though, with huge fonts for the bookmark bar and top menu I worked around this by starting chrome with /usr/bin/chromium %U --force-device-scale-factor=1.5 Maybe, if only Thunderbird is affected for you, there is a similar setting for starting that? Another work around is to alter your fonts to work with a program, start the software and then alter them back so other programs work as wanted too, harsh way to do it though.
>From Chromiums old bug reports https://bugs.chromium.org/p/chromium/issues/detail?id=375824#c65 this was deemed to be the issue back in 2014: "Use GtkSettings's gtk-xft-dpi property to convert Pango font descriptions from points to pixels. Previously PangoContext's default resolution, which is sometimes (always?) unset, was used, resulting in 96 DPI being used for conversions regardless of the value reported by X."
