Open maximized window animation not the same for Wayland and X11 clients
When opening a new maximized window the animation is not the same for Wayland clients as it used to be for X11/XWayland clients. X11 client animations start the bottom-centre, while the Wayland animations start at the top-left. Animations of floating windows start at the bottom-centre of the window, on both protocols, so I assume bottom-centre is the desired behaviour.
