That sounds strange. Cannot reproduce, and I use this effect every day so I always notice regressions. Can you by any chance capture it in the screen recording or even a shakycam phone video?

I can't reproduce it on my laptop. It was likely on my desktop. I'll check at some point again in the near future when I have 6 on my desktop again.
