Comment 24 for bug 1745888

On Cosmic, running on physical hardware, I ~did~ experience the issue with the app grid using gnome-shell 3.30.1-2ubuntu1. So I do not think Cosmic is immune to this issue.

However, I just tested the proposed gnome-shell version 3.30.1-2ubuntu1.18.10.1 in Cosmic.

With the proposed version...
1. The app grid works as expected
2. The favorites icons work as expected

I did notice an odd behavior...
May be it warrants as separate bug report?
Nevertheless, I'll share it here in case others run into this as well.

1. Give a long press on a favorites icon.
2. The icon becomes opaque (as if it is ready to be moved on the dock).
3. The context menu (New Window, Preferences, Remove from Favorites, etc.) appears.
4. Select New Window.
5. A new window opens.

6. Then tap a different favorites icon.
7. Instead of opening the application, the context menu appears.
8. I am then unable to make a selection from the context menu.

9. Sometimes the icon gets moved from its position on the dock.
10. But it doesn't land back on the dock. Instead it is partially on the dock and partially on the desktop.
11. At this point, the desktop becomes unresponsive.

    Alt-F2 does not work.
    Mouse clicking does not work.
    Touch screen does not work.

    Ctrl-Alt-F1 ~does~ work, and you can use the GDM screen to reboot the machine.
