Long overdue. Not going to help with applications that do not support it (I'm looking at you Java: #705), but will probably help with many other well behaved applications: Window Manager Protocols: _NET_WM_SYNC_REQUEST
Problem is that gdk.Window enable-synchronized-configure is that Toplevel GTK+ windows automatically use this protocol.
And there is no easy way to disable this, here's the check we could hijack:
impl = GDK_WINDOW_IMPL_X11 (((GdkWindowObject *)window)->impl); if (!impl->use_synchronized_configure) return;
By accessing the underlying X11 window object.
Problem is that the call to
gdk_window_configure_finished is embedded deep in the
And so it might just be easier to not use GTK at all...
