I'm using Ubuntu 17.10 and this bug is still present with Xorg AND Wayland.
Apps with a "normal" GTK titlebar (the narrow one), like Firefox, are working according to the settings in Gnome Tweak. So a double- or middle-click on the titlebar maximizes the window f.i. vertically. But when an app has a "Gnome" titlebar (the broad one), f.i. Gedit, then the window is always maximized fully, not only vertically or horizontally. You can download a screencast of this bug here: https://mega.nz/#!j5BSjaSL!o7E3Kuf061sJQ_tUukpe-3Tf4JTi7NExB3uI-z_ijX4 It shows the behavior of different apps, GTK and QT, with different titlebars: Deluge (GTK): works Qpdfview (QT): works LibreOffice (GTK): works Gnome Tweak: fails Gedit: fails Can somebody confirm this? Would be great to have a fix soon, since this bug is around for years! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1698083 Title: Middle-click titlebar actions (like maximizing vertically) don't work in Wayland sessions To manage notifications about this bug go to: https://bugs.launchpad.net/gtk/+bug/1698083/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
