Broadway Gtk3 backend
Ubuntu
In a terminal, run:
broadwayd
In another terminal, run:
GDK_BACKEND=broadway UBUNTU_MENUPROXY= LIBOVERLAY_SCROLLBAR=0 gedit
Finally, open you Web browser and go to:
http://localhost:8080/
The "UBUNTU_MENUPROXY= LIBOVERLAY_SCROLLBAR=0" is only useful if you use the global-menu and/or overlay-scrollbars. You have to disable them for Broadway, otherwise the program will segfault.
Please see the "broadwayd" manpage for more information.
