You probably want to call gtk_widget_queue_draw() after updating the
particles.

Hello, I'm making a particle system using gtkglext but I have ran into a
problem. Whenever I run my program it only updates the scene when the window
is not in focus. Meaning once a few particles are drawn it stops updating
the window. I have click on another window and drag it and only than do I
see the scene being updated.
My setup is simple:
/* Initialize, Resize, and Render */
g_signal_connect_after (G_OBJECT (gtkinit->drawing_area), "realize",
G_CALLBACK (InitGL), NULL);
g_signal_connect (G_OBJECT (gtkinit->drawing_area), "configure_event",
G_CALLBACK (ResizeWin), NULL);
g_signal_connect (G_OBJECT (gtkinit->drawing_area), "expose_event",
G_CALLBACK (DrawScene), NULL);
/* Show the Program */
gtk_container_add(GTK_CONTAINER(winInit.window), winInit.drawing_area);
gtk_widget_show (winInit.drawing_area);
gtk_widget_show (winInit.window);
gtk_main();
During expose_event I call two functions which update the particles.
