Scrolling in Safari 14.0.1 and Big Sur Jerky

I'm also facing the same issue. Please get this fixed. The problem occurs when scrolling a modal window like a dropdown list or anything that has an overflow function in it and the body or the parent element must stay in place (parent is overflowing but the child has an independent overflow as well).

The issue is the same but can be achieved two ways:

1. If quickly scrolled to top or bottom -> the scroll flickers
2. If scrolling over the top or bottom boundaries of overscrolling element "elastic / rubber band scroll" (didn't try x-axis scrolls) -> the scroll flickers

Ps. This is happening at least with following setups:

1. Big Sur 11.01.1 with Safari 14.0.1
2. Catalina 10.15.7 with Safari 14.0.1

I am also having the same problem. It seems to be most apparent on websites with a lot of graphics. It's uncomfortable on the eyes to say the least. I hope this gets a fix. I did a clean install and haven't added much back at all and am using zero extensions at this time.

Thank you for sharing your experience going back to Catalina. I was almost considering this and it would have been a waste of time. It seems to be an issue with Safari and not the OS.

Overall Big Sur has been a disappointment for me. It's my fault for assuming it would run fine on my old 2015 MacBook Pro 13 base model 🙄

Aside from Safari with it's scrolling issues, what really drives me nuts is that most of my mouse clicks take about a full second to register. This results in me thinking I did a "missed click" and clicking again, which results in whatever I click on getting clicked on twice. It's annoying and time wasting to say the least.

I've just installed Safari 14.0.2 and the problem didn't go away :( Still choppy and jerky...

Came here hoping for an answer 🤷🏻‍♂️

I have this issue in Safari too. It appears to happen only on YouTube, at least for me. Sometimes it "fixes" itself when I expand the video description, but even getting to that "Show More" link is hard most of the time.

I'm using Big Sur on a 2015 MacBook Pro 13 base model. It worked fine on Catalina.

Hello! I have the same issue with Safari 14.0.1 :( I've moved to MacOS Catalina (latest version) on a Macbook Pro mid 2012. The same websites in Google Chrome work smooth, but on Safari I instantly noticed that something is wrong, cause my eyes hurt from this choppy scrolling, especially on Facebook, Instagram and YouTube. How can I solve this issue? What steps we should do to get it run properly?! I don't want to move to Google Chrome, but I can't revert to Safari 13 without using hacks and tricks which i don't want to apply.
