--- Comment #9 from kdde....@porcupinefactory.org --- > Can you put some debug in KWidnwSystem::windowChanged and find out? How to do that? Is it possible to do that without recompiling, e.g. some LD_PRELOAD trick? If not, what's the minimal set of things and easiest way to recompile? You explained where 30% + 15% CPU time goes, do you have any ideas as to where the other 50-55% goes? 50% CPU usage while copying is still very bad. -- You are receiving this mail because: You are watching all bug changes.
