Kdenlive Flatpak Environment Variable Breaks the App

OS: Fedora 44 Workstation
DE: GNOME 50.4
Kdenlive Version: Latest Flatpak

Hi there,

I’ve realized that setting the environment variable QT_SCALE_FACTOR for kendlive from flatpak breaks the app on my system. The default value for the environment variable is 1, and anything below it makes the app unresponsive in the menu buttons such as File, Edit etc.

My DE is set to 125% scaling, thus Kdenlive also runs at that scale factor. However I would like it to be a little smaller for this certain application. Setting the environment variable seems to be to only way to achieve this since there is no dedicated setting to change UI scaling in Kdenlive.

For context, this is the exact command I use to set the environment variable:
flatpak override --user --env=QT_SCALE_FACTOR=0.8 org.kde.Kdenlive

Is there a way to confiuge UI scaling in any other way? If not, I am also happy to just report the bug here. If I need to open a ticket or send the bug report elsewhere, please let me know.
