+Subject: [PATCH] gtkimmulticontext: Handle switches between displays
+
+Currently the GtkIMMultiContext may stick to a delegate GtkIMContext
+that no longer applies after the multicontext is dissociated from
+any widget.
+
+Handle set_client_widget() so that it can handle changes between
+widgets from 2 different display, but also so the delegate is made
+NULL whenever the context has a NULL widget.
+
+Doing so, any new client widget results in a new delegate IM context
+lookup from the right GdkDisplay and GtkSettings, which avoids any
+mix up.
+
+Fixes: https://gitlab.gnome.org/GNOME/gtk/-/issues/4805
