Heavy performance issues with smooth seconds hand

It looks like that the smooth seconds hand does heavily affect system performance, as using the watch is really laggy then.

I wonder what the difference between other watch faces is, where the smooth seconds hand does not really affect system performance.

I'm using a Galaxy Watch 5 LTE running WearOS 3.5 (OneUI Watch 4.5).

Thank you very much for reporting this! I noticed this as well. But I was not able to figure out what's the reason behind this. I will keep exploring and will let you know here how things are progressing.
