Created attachment 131703 [details] Screenshot When using the Application Menu entry to put the toolbar under a KWin icon, Wayland spawns an entire window containing the menu, unlike X11 which provides a real menu when clicked (just like right-clicking). The WL version is difficult to work with as the window spawns in random positions, sub-menus further spawn their own windows when hovered over, whereas the windows easily disappear when unintentionally defocused. The attached screenshot shows the difference in the upper-left corner of each shot.
Still an issue in Plasma 5.20.0 / Framework 5.75.0.
