Was this working okay in 6.0 and regressed in 6.1.2?

Yes! I could observe this in both of my arch based KDE plasma systems that I recently both updated one after another.
Comment 4 Nate Graham 2024-11-27 21:05:13 UTC 
After more performance work, anything left here is now attributable to Bug 479250, which is tracked separately. Fixing that should finish it all off.
