Nowadays how well are old-school X11 window managers doing necessary interop with the desktop bus to keep modern GTK/QT apps rendering correctly on 4K HiDPI screens? I was forced to give up on FVWM because tweaking my X resources Xft.dpi and GDK_SCALE settings for one app such as firefox in order to get it rendering correctly on a 4K screen would break other apps. Firefox only seemed to do HiDPI correctly when run under a full GNOME desktop that provides the dbus messages it is assuming to set the 200% font size and UI scale correctly. Is there a way to run an old-school X11 WM now that allows snaps/flatpacks/GNOME-bloat dbus apps to run without issue with 200% scaling on 4K screens?
