+Subject: [PATCH] gdk: Clear GL context when window is withdrawn
+
+Some clients (e.g. gnome-online-accounts) quickly unmap and map
+a window. With some backends the backend surface will be replaced
+causing the application to crash because the GL context is still
+using the old surface. Clearing the GL context when a window is
+withdrawn fixes this.
