--- Comment #7 from emohr <fritzib...@gmx.net> --- Now it gets interesting. Yes we have still a performance issue on the timeline which we don't know the root cause. I tested with a short clip: track thumbnails -> all frames. Cut the clip with the razor tool in the middle. All thumbnails to the right of the cut are rebuild and displayed. Stay with the AppImage. Could you make a test with short clip (20sec, 3min)? I think we can stay within this bug and change the title afterwards. -- You are receiving this mail because: You are watching all bug changes.
