After an apt-upgrade, my KDE dock/task manager icons in Kubuntu are all black

ru flag

I recently ran do-release-upgrade to upgrade to Kubuntu 21.04 from 20.04 without issue. Other than some (expected) differences in configuration files, nothing failed. When I logged in to plasma, I was surprised to see all the sys tray's icons have been replaced with black placeholder squares -- see screenshot below. This is true even in alternative widgets, and in the the application launcher (all the icons are black squares).

There's nothing obvious in /var/log/syslog and I have an AMD gpu, which can happily run glxgears. The closest thing to a relevant error message is

Jun 14 22:01:49 localhost org.kde.KScreen[6021]: kscreen.xcb.helper: Event Error:  147

I'd love some help debugging this. Does anyone have any ideas? Should I report this to the devs, or will I be a hindrance?

Mods, feel free to close this -- apologies; it is a dupe of this question (albeit in disguise!): Black icons after reinstalling Kubuntu desktop

A quick installation of sudo apt install libqt5quick5 fixed the problem. Do'h.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
