In essence, this happens when the window is "half-maximized" (i.e., vertically or horizontally maximized). Then clicking on the (un)maximize button will unmaximize completely while the user expects a full maximize behaviour.
You can reproduce this also by middle-clicking the maximize button and then left-clicking the maximize button. You get: window normal size -> window vertically maximized -> window normal size While you'd expect (at least me!): window normal size -> window vertically maximized -> window fully maximized So the (un)maximize button should treat half-maximized windows as non- maximized (but without remembering the current dimensions for when it will be normal size again). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/953944 Title: Maximize button not working properly!
