Created attachment 108866 [details] kdenlive with system monitor Hi, I don't know exactly since when (17.0.2 ??) but now kdenlive is unuseable. Remove old config file, cache. Do a fresh start -> high cpu usage with nothing loaded ! On a core 2 due cpu is around 65% (opensuse Leap) On a athlon 860k, one core at 100%, total cpu usage around 30% (opensuse Tumbeweed). Screenshot and strace ouput attached !
