I have a report that gtk3-demo suffers the same problem but Unity applications don't. Are you sure these were GNOME applications? I wonder whether Ubuntu has a modified libgtk-3 to listen to changes in GSettings com.ubuntu.user- interface scale-factor or dconf /com/ubuntu/user-interface/scale-factor. man 7 dconf says "The dconf API is not particularly friendly, and is not guaranteed to be stable. Because of this and the lack of portability, you almost certainly want to use some sort of wrapper API around it. The wrapper API used by GTK+ and GNOME applications is GSettings[1], which is included as part of GLib. GSettings has backends for Windows (using the registry) and Mac OS (using property lists) as well as its dconf backend and is the proper API to use for graphical applications." but last I looked GSettings was only really appropriate for application settings, because there wasn't a good way to test for the presence of settings. I wonder whether there is a better way to get system settings. Perhaps there is a system daemon that reads the GSettings and notifies dbus listeners. I haven't yet found documentation on these settings. https://bugs.eclipse.org/bugs/show_bug.cgi?id=489771 http://askubuntu.com/questions/510457/how-do-i-get-the-value-of-display-scale-for-menu-and-title-bars-from-the-c Reply at: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1730980/comments/8 ------------------------------------------------------------------------ On 2017-06-19T14:55:43+00:00 Kohei-yoshino wrote: *** Bug 1374311 has been marked as a duplicate of this bug. *** Reply at: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1730980/comments/9 ------------------------------------------------------------------------ On 2017-12-29T11:31:47+00:00 Jeppe Bundsgaard wrote: Did you ever find a solution for this bug?
