Ubuntu-dock in Wayland slow

[Jan Morten Rausch]

Only in Ubuntu's wayland session, on 20.04 and 20.10:

App icons will appear with a massive delay (~10 seconds) after launching an app currently not in the favorites.

Also moving pinned icons within the dock will only appear in the new location after a similar long time span. Otherwise the dock works without delays.

I could see this behavior on two completely different machines. No problems in the default Xorg session.

Please mark this bug as duplicate of

Bug #1874578

Saw the bug report to late.

Issue immediately vanishes after hiding mounted devices in the dock with:

gsettings set org.gnome.shell.extensions.dash-to-dock show-mounts false
