Gdk-Message: 09:50:28.438: Error 71 (Protocol error) dispatching to Wayland display. Running it with WAYLAND_DEBUG=1, the underlying error message that GDK seems to eat is: [3471970.531] wl_display@1.error(zxdg_imported_v1@36, 0, "set_parent_of was called with an invalid child") That is, when it tries to associate the dialog box with the confined application's window. It seems the underlying bug is in in Mutter: https://gitlab.gnome.org/GNOME/mutter/issues/138 According to duflu, the patch referenced in that bug report has been merged for 3.28.2 and 3.29.2. It seems like a candidate to backport to bionic if we want portals to work on the (non-default) Wayland session.
