Hello, I have noticed something for a while now, and it hasn't improved with XFree86 4.0 I use the 3D screensaver Morph3D (GL). It starts of at quite a good rate, but after 10 - 15 seconds slows down to a complete crawl. Now for the new bit : I downloaded the latest Mesa and Mesa Demos the other day and as I tend to do I ran some of the Demos (just to see how things are improving !). I was running Morph3D and I noticed the same thing happened. At the time my mouse was hovering some where over the middle of the Morph3D window. As I moved the mouse accross the window I noticed the animation speeded up again ! Yes, really. No, I am not taking anything ! When the mouse stopped animation slowed to a crawl again. This also worked in other Mesa demos, keep moving the mouse and animation is really smooth, stop and it isn't. I don't know if I should flag this up here, or with the XFree86 lot, or if its a well known situation, or if I should just shut up ! I have since tried this on another machine with a different video card, so I don't think it's just my machine. Any one got any idea what is going on here. Owen
