Comment 3 emohr 2018-12-11 19:32:41 UTC 
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
