So I hacked together a small test in plain C. But again, I can not see a difference for my Box. (Linux AMD64, Gtk3.12, Gnome3, X11, AMDX2 CPU, nvidia-drivers ...) Here is the C code and the output, event time delta is general 12 ms with few exceptions, no matter if compression is enabled or disabled. /* http://zetcode.com/tutorials/gtktutorial/firstprograms/ */ #include <gtk/gtk.h> void print_event(GtkWidget *widget, GdkEventMotion *event, gpointer p) { printf("%.0f, %.0f: %d\n", event->x, event->y, event->time); } int main( int argc, char *argv[]) { GtkWidget *window; GdkWindow *gdkwin; gtk_init(&argc, &argv); window = gtk_window_new(GTK_WINDOW_TOPLEVEL); gtk_window_set_default_size(GTK_WINDOW(window), 800, 800); gtk_widget_set_events(window, GDK_POINTER_MOTION_MASK); gtk_widget_show(window); g_signal_connect(window, "motion_notify_event", G_CALLBACK (print_event), NULL); g_signal_connect_swapped(G_OBJECT(window), "destroy", G_CALLBACK(gtk_main_quit), NULL); gdkwin = gtk_widget_get_window(window); // gdk_window_set_event_compression(gdkwin, FALSE); gdk_window_set_event_compression(gdkwin, TRUE); gtk_main(); return 0; } 36, 422: 42037389 36, 426: 42037401 48, 438: 42037413 62, 451: 42037432 79, 464: 42037437 102, 475: 42037455 129, 486: 42037465 150, 493: 42037477 179, 500: 42037489 206, 502: 42037501 233, 502: 42037513 262, 502: 42037525 285, 491: 42037537 314, 480: 42037549 343, 469: 42037566 372, 460: 42037577 391, 447: 42037589 406, 430: 42037601 421, 413: 42037613 436, 396: 42037631 447, 377: 42037637 _______________________________________________ gtk-list mailing list gtk-list@xxxxxxxxx https://mail.gnome.org/mailman/listinfo/gtk-list
