Function bubble_show() is busy polling redraw_handler and pointer_update at 60Hz. The code should wait for motion notify events only in the area surrounding the notification area and only then handle updates rather than spinning on a 60hz poll. // FIXME: do nasty busy-polling rendering in the drawing-area priv->draw_handler_id = g_timeout_add (1000/FPS, (GSourceFunc) redraw_handler, self); // FIXME: read out current mouse-pointer position every 1/25 second priv->pointer_update_id = g_timeout_add (1000/FPS, (GSourceFunc) pointer_update, self); The above code is running two sets of 60Hz polls and could be at least combined since they run at the same rate to be wasteful in polled mode. However, it should be fixed correctly not to poll in the first place. To observe this fault, strace notify-osd and observe the insane amount of poll() calls.
