Canceling that removes X’s CPU usage. That's a GTK+ spinner widget, which uses RENDER trapezoids, which is a software rendering fallback with EXA. > Should I recommend something to the Evolution folks on how to due such > animations? Or is the only way to avoid animations? I don't think there's anything wrong with the animation per se. However, one issue I've found is that Evolution schedules many actions as glib idle callbacks with priority lower than G_PRIORITY_HIGH_IDLE + 20, which is the priority used by GTK+ for drawing animations. This can result in the animations delaying the completion of the actual work they're representing. -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Debian, X and DRI developer
