@mt Nothing. But when I start it from command line:
jocc@gep1deb:~$ /usr/bin/flatpak run --branch=master --arch=x86_64 --command=va-builder com.visionappster.Builder Qt: Session management error: None of the authentication protocols specified are supported qml: Could not start web server. Model size of -784 is less than 0 Model size of -112 is less than 0
The first 2 is immediately at start, the last 2 (Model size...) are written at the moment of "Add images" !
