Sometimes (I can’t pinpoint the trigger), when logging in after waking from suspend, gnome hangs on the login screen for a few minutes before returning to the login screen. When I log back in I have lost my previous session (all programs close). Sometimes I can log in from suspend without any issues.

gnome-session 3.24.1-1
gnome-shell 3.24.2-1
