SUMMARY These apps are not even running. This is very likely caused by the switch from pulseaudio to pipewire on Arch Linux by default. SOFTWARE/OS VERSIONS KDE Frameworks Version: 5.76 Qt Version: 5.15.2
I don't have this issue anymore, I will investigate how to trigger it again.
Most likely the same root cause as Bug 417457. Duping for now. *** This bug has been marked as a duplicate of bug 417457 ***
