Hi Paul, thanks for pointing me to this bug from https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1827791.
Is this also on a Dell XPS 13 9380? Your comment about Wayland made me curious, as I was using the default Xorg session. Testing with Wayland on 19.04 I also see the same problem (actually I think it's more prominent with Wayland than it was with Xorg). I also see lines like this in journalctl -b0: May 13 21:34:46 daniel-XPS-13-9380 org.gnome.Shell.desktop[1673]: Window manager warning: last_user_time (242191) is greater than comparison timestamp (242190). This most likely represents a buggy client sending inaccurate timestamps in messages such as _NET_ACTIVE_WINDOW. Trying to work around...
