I think it's an Emacs problem, because it is not behaving as configured, even though other GTK applications do. > Are the binaries used on both machines from the same build? Indeed, it is the same binary on the same machine, I just switch desktop environments. If I switch from i3 (an X11 WM) to GNOME3, Emacs uses subpixel rendering, whereas other packages use it under both scenarios. > If not, please show the value of system-configuration-features from > both builds.
