With all the stuff Gtk3 is doing, maybe it should be GNOME-exclusive
and let everyone else continue using what has been working properly,
albeit without HiDPI, if you need that.

I also checked gtk3-widget-factory as found in arch stable (3.20),
and Raleigh is totally broken. No custom theme, just selecting
Raleigh as theme (engine) and menus are totally broken.
I didn't try in GNOME, but I use Gtk3 because apps use it,
not because I want GNOME. Of course, this also means I had to
port my colour-customization Raleigh theme again, but it's equally
broken as the built-in Raleigh theme. I'm not even mentioning that
I found no way to configure scrollbar buttons as I do in my gtk2 theme.

Qt5 has a 30MB base overhead for any app (window), but
it didn't break randomly from Qt4 to Qt5 for the apps I use
it in.

I have no idea what's going with Gtk3, but I never once had such
issues with either Gtk1 or Gtk2. Strange new world...
