Please try with the actual Kdenlive AppImage version 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 2 Henrik Härkönen 2019-05-27 17:28:51 UTC 
I'm having this same behavior with version 18.12.3 in Kubuntu 19.04.

Using:
MLT version 6.12.0
FFmpeg libraries

KDE Frameworks 5.56.0
Qt 5.12.2 (built against 5.12.2)
The xcb windowing system
Comment 3 Henrik Härkönen 2019-05-27 19:15:30 UTC 
Same result with the latest AppImage:  kdenlive-19.04.1c-x86_64.appimage
Comment 4 Simen Russnes 2019-11-09 09:21:13 UTC 
Still happens on Fedora 31, Kdenlive from RPMFusion repos version 19.08.2
Comment 5 Julius Künzel 2021-03-16 19:31:06 UTC 
Can you please update to the latest version (20.12.3 at the moment, https://kdenlive.org/en/download/) and report here whether this is still happening?

Just out of curiosity I have a few questions about your usage of the DVD Wizard: Do you still create DVDs? Do you still use Kdenlive for that job? Have you ever tried a different (maybe more specialized) Tool for DVD creation?
Comment 6 Carlo Borger 2021-03-16 21:04:18 UTC 
Created attachment 136752 [details]
attachment-13584-0.html

Hello Julius,
In the past year I was not able to create any video as we were not able to roll out our yearly festivity with handicapped people.
So I had no video to create and as a result of that no dvds to create to.
But maybe it is a good idea to use another tool to create a dvd, I can dive in to that to figure it out.

Comment 7 Julius Künzel 2021-03-25 15:57:28 UTC 
Thanks for your answer Carlo! We are currently discussing if it is worth to keep the DVD Wizard in kdenlive or if we should drop it. The discussion is at https://invent.kde.org/multimedia/kdenlive/-/issues/1005.
