Comment 0 for bug 1944431

What Happened
1) Installed the package gnome-session (ensuring it is the latest version)
2) At gdm picked "GNOME" and not "Ubuntu"
3) Reboot and login to the desktop
4) Notice that initially the activity overview is shown (correctly)
5) Then within a second or so, something causes the desktop to be focused and activity overview closed (incorrect)

Further notes:
- if you log out and log back in again, it doesn't happen ?
- if you wait on the gdm login for a long period of time (eg over a minute) then it doesn't happen ?
- this is *not* the Ubuntu session but the GNOME session

What I expected to happen:
At step 5 for the activity overview to stay and not switch to the desktop until the user has interacted.

I understand that the Ubuntu session with the dock enabled wants the desktop to be the current state after login. But for the GNOME session with no extensions enabled, the way that if one logs in quickly and something is triggering the activity overview to be dismissed appears to be a bug.
