I found a problem with lagging on new snapshot 20w22a on macOS.
I'm playing on Macbook air 13 (2013). In previous snapshot I had at least 40-50 fps while playing. Now the number of fps is somewhere around 14-20. I just can't play this snapshot. I believe it's some kind of bug.
Thank you for your report!
