Bug#1023174: plasma-desktop: Plasma toolbar tooltip window previews not working under wayland: module "org.kde.pipewire" is not installed

[Ralf Jung]

Package: plasma-desktop
Version: 4:5.26.0-1
Severity: normal

Dear Maintainer,

when starting a Plasma Wayland session, window previews are missing in the toolbar tooltips.
This is probably related to the fact that the following shows up in the logs:

file:///usr/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/PipeWireThumbnail.qml:11:1: module "org.kde.pipewire" is not installed

Looks like a missing dependency somewhere? I tried installing libkpipewire by hand but that did not help.

Kind regards,
Ralf

plasma-desktop suggests no packages.

-- no debconf information

[Frederic Parrenin]

The solution is to install the following package:

qml-module-org-kde-pipewire

So this package should probably be included in the Plasma dependencies.

[Ralf Jung]

Turns out the missing package is "qml-module-org-kde-pipewire". It should be
added as a dependency of plasma-desktop.
