20.04 Slow icons in dock

[Tero Gusto]

If I open a program, it opens right away, as expected. But it takes around twenty seconds before its icon is shown in the dock, together with the other running applications.

The same thing happens if I close an application, the icon doesn't disappear right away, but after around 20 seconds.

Sounds like another case of bug 1874578.

The difference here is that I do have a disk mounted automatically via /etc/fstab when booting, but both show-mounts enabled and disabled are delayed.

Status changed to 'Confirmed' because the bug affects multiple users.

This effects the currently released Ubuntu 21.04. It takes 20 seconds for icons to appear on dock.

I am also having this issue on a fresh install of 21.04:

* Occurs when booting with a USB stick already plugged in.
* Does not occur if booted without the USB stick.
* Does not occur if booted without the USB stick, then plugged in post-boot.

Its fixed with current updates and gnome 40:
$ apt policy gnome-shell
gnome-shell:
  Installed: 40.2-1ubuntu1
  Candidate: 40.2-1ubuntu1
  Version table:
 *** 40.2-1ubuntu1 500
        500 http://us.archive.ubuntu.com/ubuntu impish/main amd64 Packages
        100 /var/lib/dpkg/status

No more slow dock icons!

Oops. I was on 21.10 using older gnome 38. Not sure about 20.04. I don't think they will get gnome 40.

Thanks, good to hear that it might work in the future :-)
