Does anyone know if it is possible at all to display the global menubar in apps from the main ubuntu repository? I have found very odd that is missing in apps like pinta (show below), GIMP or Gpaint
While present (not as neat as in Unity) in other apps not in the the main Ubuntu repository (e.g. TexStudio).
I am aware of the existence of an extension to show the global menu bar (as shown in this question), however, I want to know why some apps are still showing the menubar while other are not and, most importantly, whether there is a solution for that.

If you have have installed Gnome Global Application Menu(HUD for Gnome) extension mentioned in this answer to the other question you've linked, you'll need to reset a couple of
gsettings
keys after disabling/uninstalling the extension to restore normalcy.Open Terminal and run the following commands
Then reboot.
