Different height for headerbar in one app

[Michal Predotka]

Ubuntu 17.10 Beta running live from USB

I admit I have no idea how that "top bar" decoration of windows is called. Is it "tittle bar" or "tool bar"? Anyway I'm talking about that dark part with minimize and close buttons on it.

I noticed the height of that bar is different if there's no additional buttons and different if there is an extra button or two. For example in the Settings app go to Details and switch between Users and Default Application tabs. When you're in Users tab you will see Add User button in the top bar. There's no button in the top bar of Default Application. When you switch between those two tabs you will notice that the top bar for Users tab has bigger height. And that gives visually unpleasant effect of interface jumping up and down when switching tabs.

Short video attached.

Thanks for reporting this bug and help making ubuntu better!

I don't know if this bug is special to the ubuntu session or related to the application. Something to check:
- installing the gnome vanilla session (sudo apt install gnome-session), reboot and switch to the "GNOME" session in GDM.
- you should have the Adwaita theme there. Check if you can reproduce the bug
- please report here if you can reproduce it. If there is a bug in that session, do you mind filing the bug against upstream bugzilla in gnome-control-center.

PS: the name is "headerbar" :)

This bug is Ubuntu-specific and doesn't occur in Adwaita. Probably caused by my Ambiance headerbar theme changes from a couple of months ago.
