So here is the upstream answer:
Window decorations are client-side on wayland, that means they are just another part of the application window the same way as the products you are viewing. We cannot tell what parts of the window are decorations, or whether there are in fact any decorations at all. It's entirely up to applications to adjust to window state changes if they desire. (In the X11 session, there is a _GTK_HIDE_TITLEBAR_WHEN_MAXIMIZED hint that applications can set, and you'll find extensions that apply that to any windows. But X11 is a legacy technology at this point, and we won't add any features based on that.) As Ubuntu 18.04 is a LTS release still using X11 for compatibility can the Ubuntu project please add the _GTK_HIDE_TITLEBAR_WHEN_MAXIMIZED hint as a toggle? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1787288 Title: gnome-shell window title bar wastes space when maximized Status in gnome-shell package in Ubuntu: Incomplete Bug description: Steps to reproduce Start Ubuntu Login to Unity Choose logoff Choose Ubuntu (which should have the label Gnome-hell) Note this is the only way to get Gnome-hell to start, starting it directly just shows a black screen and dumps you back to the greeter. (already created a bug report for that) Open a program Choose the Maximize icon alllll the way over on the right (thanks Gnome-shell devs for causing more Mouse Arm for people with Hi-res screens, instead of just moving the mouse up to the top to click my button, I now have to move it all the way across the screen to the right) The window maximizes but not to full screen. I get a weird double bar, with the clock bar and the window title bar wasting valuable pixels. On my professional systems at work, this means I can display one less product on the screen, products being more important than the titel of the window. Please hide the window title when maximized.
