Bug#1120834: pitivi: Pitivi render window remains unattached

[guy]

Package: pitivi
Version: 023.03-3
Severity: important
X-Debbugs-Cc: grandtoubab at msn.com

When Pitivi starts the render window appears out of the gui and can't be
reattached.
So the application Pitivi is unusable on Debian/Gnome.
It looks like "viewer: Fix a race where gtksink is started before being
embedded in the UI" https://gitlab.gnome.org/GNOME/pitivi/-/merge_requests/485

I have to install the Flatpak version of Pitivi to be able to use it on my
Debian PC.
