I tried to install the update. I haven't done this before, so just to make sure I'm in the right state:
$ apt list gnome-shell-extension-ubuntu-dock -a Listing... Done gnome-shell-extension-ubuntu-dock/focal-proposed,focal-proposed,now 68ubuntu1~20.04.1 all [installed,automatic] gnome-shell-extension-ubuntu-dock/focal,focal 67ubuntu20.04.5 all This looks correct, right? I then triggered the bug again by removing all "Favorite" Applications, and switching to a Workspace without any applications. And the bug happened again: $ journalctl -f Jun 04 11:03:29 xyz boltd[2397]: power: setting force_power to OFF Jun 04 11:03:29 xyz boltd[2397]: power: state changed: supported/off Jun 04 11:03:29 xyz kernel: xhci_hcd 0000:3c:00.0: Refused to change power state, currently in D3 Jun 04 11:03:29 xyz gnome-shell[2002]: JS ERROR: TypeError: firstIcon is undefined _adjustIconSize@/usr/share/gnome-shell/extensions/ubuntu-d...@ubuntu.com/dash.js:612:9 _redisplay@/usr/share/gnome-shell/extensions/ubuntu-d...@ubuntu.com/dash.js:841:14 _runDeferredWork@resource:///org/gnome/shell/ui/main.js:689:31 _runBeforeRedrawQueue@resource:///org/gnome/shell/ui/main.js:704:9 _queueBeforeRedraw/<@resource:///org/gnome/shell/ui/main.js:713:13 Jun 04 11:03:30 xyz kernel: xhci_hcd 0000:3c:00.0: Refused to change power state, currently in D3 Jun 04 11:03:30 xyz kernel: xhci_hcd 0000:3c:00.0: Controller not ready at resume -19 Jun 04 11:03:30 xyz kernel: xhci_hcd 0000:3c:00.0: PCI post-resume error -19!

However restarting with `alt`+`F2` -> "r" -> `enter`, fixes the problem temporarily, just to come back shortly after. At first I thought it was something caused by my update to 20.04, but it even happens with a fresh install (dock location is at the bottom). I think there are multiple ways to trigger this behavior, but what worked reliably so far is to close the last running application, so that the dock is completely empty (no favorite applications in the dock - only the "Show applications" button on the dock). So far this triggered the bug every time, but I'm quite sure there were also other ways to get into this "dock no longer/delayed updating" state with other means.
