After setting option smooth into false, it is still not working.

here is the reproduced video

you can see that it's not scrolled to the latest message and can only scroll the list by dragging the scrollbar.

here is the normal behavior

Let me know if you've seen the GIF, I need to delete it...

ps: can we speak Chinese,pls?

@twoKilo

Sorry, I don't have Windows OS in my Macbook Pro, so I need your help with debugging. Is there any error on the console tab of your Google Dev Tools? Does the scrollto and the startitem work?

You can delete the GIFs.

I think we'd better use English for the issue because this issue might help others someday.

@wellyshen
No, there is no error either on the console or Dev tool. I will test the functionality of scrollTo later, but I can't use startItem cause I am using version 0.5.5, and upgrading a package in my company takes some efforts... But do let me know if you want it to be verified.

Also, I've received a feedback from test team that the auto scroll feature is not working on Sogou browser(speed version) which is achieved by using scrollToItem api. And I've tried the scrollTo, it's working as expected on Sogou browser.

Currently I am also on MacOS, I'll get back to you with a reproducing demo on Sogou browser as soon as I can.

Debugging can wait ; )

@twoKilo Can you upgrade to the latest version then test these methods locally? I think we can focus on Google Chrome first because Sogou is based on Chromium.

from react-cool-virtual.

@wellyshen I've upgraded to the 0.6.0 version, and tested on Windows (smooth scroll enabled), and scrollToItem is still not working.

I think Sogou does not share the same issue with Chrome on Windows(smooth scroll enabled). But okay, we can focus on the topic issue first. Still I hope you can look into Sogou issue anyway.

Appreciated.

@twoKilo How about the startItem and scrollTo do them work? BTW, the latest version is v0.7.0.

from react-cool-virtual.

@wellyshen I've updated to v0.7.0, and tested on Windows (smooth scroll enabled), scrollToItem and startItem both not working. scrollTo is working as expected.

@twoKilo Have you enabled the smooth: true when trying the scrollToItem and scrollTo methods?

from react-cool-virtual.

@twoKilo I have gotten a Windows laptop, will investigate this issue soon.

from react-cool-virtual.

@twoKilo Sorry I'm busying recently. Will investigate this issue once I have time.

@twoKilo Hey mate, sorry for the late response. I tried to reproduce this issue on Windows 11 + Chrome + smooth scrolling enabled, but I can't reproduce it. Did I miss something?

from react-cool-virtual.

@twoKilo Feel free to re-open it if you still encounter this problem.

@wellyshen Idk if it the same, but I faced issue when scrollBehavior: "smooth" set to outer and if you have "light" data it will start lagging about on 300th element, but in work i have heavy one and I faced it from start. There example forked from RCV examples. Of course there are no issue when we delete scrollBehavior: "smooth" from outer
