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).
