Summary

0002333: Adding speed to video clip makes some vanish

Description

I have a video project where I have multiple video clips and picture together. From time to time when using speed effect the video clip (or a picture near it in the video track) "vanish" from UI (eg doesn't show it in track but nothing can be put over them either). Only way to bring them back is by closing and reopening the kdenlive. This time the kdenlive crashed just after this so I got a backtrace of the event.

I used the version in the ubuntu package repository given on kdenlive website (and not the version which is in kubuntu repos).
