If anyone has problems with Audacious crackling at high CPU loads after this upgrade, go into its settings, select audio and change the output plug-in from PipeWire to PulseAudio. That fixes it.
Latest version of PipeWire 1:1.2.5 may have a bugfix for this issue, but has only been released to Unstable and Testing branches at the moment
Branch compare for Manjaro - pipewire
Unfortunately, it did nothing 
I updated two days ago but just now realized a problem with printing certain .pdf files. I usually click on a .pdf file in my Firefox browser which opens up GNOME Evince. When I try to print the file (printer is a HP Envy 4520) it sometimes miraculously works but then throws an error message “universal filter failed” for other .pdf files and halts the print.
Can anyone confirm this?
Here’s a log from /var/log/cups/error_log for one of the failed prints in case it sheds some more light on the issue:

Did some testing and it seems that printing from within Chromium is working fine. I guess Chromium is using its own software to display .pdf files.
