I set the in/out points on a video clip and drag it to the timeline - this works fine, I get a clip on the timeline based on the in/out point locations.

But at some random moments, when I'm moving things around in the timeline the points on some clips get reset to something else and it messes up the clip on the timeline!

Is this a bug? Am I doing something wrong?

On which platform and which Kdenlive version do you run? Can you reproduce this?
