Hi,
i just installed kdenlive on 25 school laptops and tried to use some of them. Editing like Importing files and voice over do work fine - but i can't save the the projekt!
There is just no menue dialog appearing. The same with the "open-Dialog".

I am using kdenlive since years on my private Linux Mint System and never had this kind of problem before.
Any ideas?
Thanks a lot!

I installed
kdenlive 20.04.0 via snap
on
Ubuntu Mate 20.04 (kernel 5.4.0-54)
and
Ubuntu Mate 18.04 (kernel 4.15.0-124)

starting from terminal gives the following when trying to open the dialog:

Some News, kdenlive-21.03.70-c42149b-x86_64.appimage seems to work. But that's a nightly. I hope it's stable enough.
I still wonder what is missing in the stable version.
Any hints?
