Some applications that use client side decorations usually set custom input shape in order to prevent drop shadows stealing pointer events from windows below. Currently, the only way to get it is to use some XFixes APIs. On the other hand, plenty of wayland compositors use solely the wl_surface input region to decide what view can receive pointer input, which results in some pointer input issues around client side drop shadows because Xwayland doesn't set wl_surface.input_region.

X Server
The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into.
Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.
