--- Comment #3 from skoupad-bugzi...@yahoo.com --- Additional info: I've just updated to Debian 9. Unfortunately the problem is still here. I was hopping that with a new clean install (and updated software) that the problem will go away. I have tested the Appimage version 17.04.1b on a clean Debian 9 fresh installation without changing anything. When I first run Kdenlive the CPU usage goes to 30%. That is with the Audio driver setting set to Automatic. If I change it to PulseAudio the CPU drops to 10%. If I add a video file the CPU usage raises up a bit. Without the video playing and without adding any filters or effects. And if I close Kdenlive completely the CPU usage returns to normal. I have also noticed that if I open the settings window (Settings > Configure Kdenlive) the CPU usage returns to normal. In fact if the focus is anywhere else than the main window of Kdenlive (for ex. in a Nautilus window) the problem goes away. If I click back to the main Kdenlive window to give it the focus then the problem is back. (Except with the Audio driver setting set to Automatic. In that case the CPU remains high). -- You are receiving this mail because: You are watching all bug changes.
