I'm using ArchLinux with DE xfce4 and the hell pulled me yesterday to run a full system update.
After the update, almost all GTK themes broke, an example of a breakdown:

And that's not all, similar jambs began to appear in many places, I immediately went to Google and stumbled upon the topic: https://manjaro.ru/blog/art_screenshots/after-obno ...

Answer 1

Read about Arch Linux Archive .

Answer 2

install the "downgrade" package and use it to roll back. For example: dwongrade qt5, for which you will get several previous versions.
