Looks like we are back at full pace with many performance fixes merged in GNOME shell and mutter and the Adwaita revamp going on. Not seen in the merge requests but still important: the long-time interface to add child widgets to a GtkBox (gtk_box_pack, gtk_box_pack_start and gtk_box_pack_end) has been removed from GTK and replaced with gtk_container_add.
