While an xdg-popup can be mapped without a parent, they cannot be positioned alone as there is no global positioning coordinates on Wayland, so you still need a parent somehow (gdk wayland works around this by trying to guess one if none was specified, based on the input seat grab and if it fails to find one, it will create a surface). So I am tempted to think if you set a parent, you don't need an xdg-popup for the general use case. And this case is covered with the above patch anyway, i.e. a temp gdk window (i.e. a GTK_WINDOW_POPUP) with a parent would be translated as a subsurface.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
