I don't have idea what package can be the responsible of the problem, but I can say that Gedit, Nautilus, Ubuntu Software or the terminal have the problem, but Libreoffice, Telegram or Thunderbird works well.

I'm not sure what the package associated with the problem might be, but it's something related to window management.

I've encountered the same problem today.

I did a little more testing, and I've observed other issues as well, some which may be related, arguably some which may be separate bugs, but I'll list them nonetheless:

* Cannot move gnome-terminal windows by dragging the title bar.
* Right clicking the gnome-terminal title bar opens the context menu, but it disappears as soon as the right mouse button is released. (As a partial workaround for the first bullet: If I hold the right mouse button, go down to "Move", and then release it, it activates the Move option and I can move the window.)
* Other windows (firefox snap, emacs) won't switch focus back to gnome-terminal easily unless you resize the window a little bit, after which they'll allow you to do so. Strangely, the same problem doesn't extend to switching between snapped firefox and emacs.
* alt-tab doesn't show any visual overlay, and only switches between the last 2 windows.
* Toggling a VPN connection via the top right hand corner menu will cause a crash and reload of the UI. (I just toggled my connection to the Canonical VPN twice, and each time I did so, this happened.)

I don't know if there's a shared underlying library that this is all related to or not; maybe these issues need to be broken apart. Nonetheless, reporting this so at least we have the info somewhere.

This looks connected to bug 1917926 so let's track it there for now.
