This is actually papering over bugs in toolkits. On X11 the Xserver will send crossing events when the stage input shape changes. As those go end up ignored in GTK+, this warp call aims (and randomly manages) to send a motion event that wouldn't go unlistened by the drag source window (the one holding the grab). This bug actually manifests in other ways, eg. by changing the window beneath the pointer with alt-tab while DnDing. This should be fixed altogether in the client side. https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/317
