TEXStudio is working in Libertine! The generation of sample documents went well. Tested on channel 24.04/daily on Fairphone 4. RAM usage topped at 2.7GB (free -h).

Other working things that are often used together with TEXStudio in the same libertine container:

• inkscape (vector graphics)
• atril (pdf viewer)
• thunar (file manager)

Other;

• mousepad (text editor)
• parole (music)

Not working as well out of the box:

• emacs
• gedit
• leafpad (usable, complaining about wayland)

Observations

• xfce software tends to work with libertine.
• Some windows get a window title bar that I didn't figure out how to get rid of.
• Some apps in libertine are in bright mode. Maybe there is a way to add dark mode theme to a libertine container.
• A libertine container can say you need to run dpkg --configure -a as root to fix an installation gone wrong. How to become root in a libertine container is not straight forward. su - not working. su phablet not working. libertine-container-manager exec -i noble -c "/bin/bash" and then fakeroot seems to work.

I would apreciate something to get rid of the cookie questions. Something like addon "I still don't care about cookies". Maybe someone knows how to achieve it.
