The posterity is that its been mentioned in the release announcement. (flagged in unstable a while ago … so technically its been in Testing Announcements, etc too) Every release since 28 days ago.
This is a bug I just experienced on one of my manjaro computers. I was puzzled as fuck because cpu/io usage wasn’t high but it was pretty slow.
Wow, I’ve had this for maybe a year now and was just living with it. Figured it was an audio thing, but Firefox only. Hopefully this fixes it.
Edit: yep, fixed! 😮💨
