Degraded performance with vue 3.4.30

[alexblunck]

I just upgraded to the newest vue version (3.4.30) and am experiencing massively degraded performance with v-calendar.

I have prepared two minimal vue apps with only the Calendar component used. In the one with vue 3.4.28 everything works perfectly fine. In the Vue 3.4.30 project however the Calendar component reacts very slowly to any user interaction (Easily testable by attempting to navigate through months).

I am also upgrading from 3.4.27 to 3.4.30 and the performance degradation is very noticeable.

Thanks, you saved me a lot of time!

Dowgrading to 3.4.29 works fine, the problem is only with 3.4.30

Had the same issue when I upgraded from 3.4.28

Seems there are some problems with 3.4.30 (e.g. #1479).
3.4.30 Changelog - changed reactivity

I think it might be in vue 3.4.29, I had to rollback to vue 3.4.28 for it to be snappy again

I have the same issue on vue: 3.4.30 and 3.4.29. I tried 3.4.28 and my Vcalendar still slow.. Any idea ?

What does your package.json look like? Check your installed version with the command npm list vue.

As a workaround, I downgraded from [email protected] to [email protected]. Seems to work.

I was at Vue 3.4.27 which worked fine and 3.4.30 didn't. (Glad to see there's already a discussion going on it!)

[email protected] also performance issue. pls check open Year popover in nav.

Vue 3.4.31 (released not even an hour ago) fixes it for me.
Looks like there was a mistake in a fix (since they reverted it) in 3.4.30 on Vue's end.

Vue 3.4.31 fixed it.
With 3.4.30 it even crashed the tab.

[TomGreen1943]

Thanks. In Vue 3.4.31 it works fine for me too.

Some one test it in production with 3.4.31 ?
