Hi All, I've observed that when some popups and most notably the kickoff menu appear on screen it does try to slide in. The problem is that it looks like a landslide, the background under the menu also slides and makes a very distracting effect. It is also very slow. Does anybody know whether there is a bug report about it, or any more information so that I can try to fix it? (I don't want to start from scratch.) Could it be a graphics driver bug? What I don't really understand that how can desktop effect be much slower with KDE than with gnome on the exact same hardware? Can somebody point me to the right direction to figure this out? Hardware is radeon rv730 (HD4670) on F13 fully updated using the mesa 7.8 drivers. Thanks, Robert
