Please try with the actual Kdenlive AppImageversion 18.08.3
Run the Appimage from the terminal (press CTRL + ALT + T). Move to the AppImage folder and run the .AppImage: ./Kdenlive*.AppImage

Comment 4 Alexander Mentyu 2018-12-13 10:40:52 UTC

Cannot reproduce both with regular neon Kdenlive 18.08.3 and AppImage packages
