Hi there, Sorry if this has been posted before, couldn't find a duplicate post about this. When Vivaldi opens a small (non-fullscreen) window for some reason, and I click on the Maximize button, nothing happens. I have to minimize it to the taskbar and then open it again, and then it's maximized. The same happens when I try the opposite. I'm using Ubuntu Studio 16.04 (xcfe destop environment) and the window control buttons are on the left side. I don't know if these have anything to do with it but I thought it's good to know.
