I have a question as well. here is a quote from Michael Torrie: First is that when you uncover a window, X11 sends expose events to the uncovered window. It is up to the client (the app) to respond to these events and redraw the parts that were exposed. If the window is in motion, these expose events may come faster than the app can deal with. GTK typically "compresses" these events and will wait to do the actual redraw. This reduces the CPU consumption and increases overall speed, but it comes at the expense of visual stuttering. " IF that is the case then why do i get Stuttering AND 100% cpu utilization? When I hold a window and move it around in little tiny circles, my cpu monitor goes up to 100% (on an amd 64 3000 ) . btw thats with no other programs running.........
