'Saved Paths' popup crashes deluge on Wayland

[pjlbyrne]

When you click on the 'Saved Paths' dropdown in the 'Move Download Folder' dialog, deluge crashes.

stderr shows: Gdk-Message: 14:36:53.552: Window 0x560dbb915830 is a temporary window without parent, application will not be able to position it on screen.

(deluge:183142): Gdk-WARNING : 14:36:53.552: Couldn't map as window 0x560dbb915830 as popup because it doesn't have a parent

Then ~13000 copies of: (deluge:183142): Gdk-WARNING : 14:36:53.553: Window 0x560dbb915830 is already mapped at the time of grabbing. gdk_seat_grab() should be used to simultanously grab input and show this popup. You may find oddities ahead.

Then: Gdk-Message: 14:36:54.581: Error 11 (Resource temporarily unavailable) dispatching to Wayland display

I'm guessing this is related to:

Quite a few applications use GTK_WINDOW_POPUP to create various temporary windows and place then on screen. That works fine on X11 but on Wayland there is no global coordinate system for regular surfaces.

If the application is using a gdk temp window and set a parent with gtk_window_transient_for(), the gdk wayland backend has all it needs to create a subsurface that can be placed at will by the application.

If I login to a 'GNOME Xorg' session this problem does not occur. So it is related to Wayland.

As pjlbyrne suggests, this is not fixable in Deluge
