In the Wayland session, smooth switching between items does not work in the global menu (when you click on an item in the global menu and move the cursor to the next one, you need to click on it again to open it) in the Xorg session, everything works fine. Also, the global menu does not work at all with GTK applications, again, everything works in Xorg.
