Well, my first posting in this thread seems to indicate a real issue, as Mr cecashon@xxxxxxx confirmed. Animation does not continue when mouse pointer is moved out of the widget and back again. Maybe that is a Wayland problem -- when it is I assume that it will be fixed some day. Maybe it is restricted to my dev-libs/wayland-1.13.0::gentoo For the g_idle_add(): As Mr E. Bassi explained, there is a different behaviour in Wayland, cursor animation does only work when main thread is idle. I will follow all your advice and start a new thread for the chess engine to return the reply move. _______________________________________________ gtk-list mailing list gtk-list@xxxxxxxxx https://mail.gnome.org/mailman/listinfo/gtk-list
