Problem in scrolling Youtube page on Safari macOS Big Sur

Apparently there’s some issues with web styling in YouTube, so this lovely person has created a temporary workaround, see image for instructions. Once you’ve installed userscripts Safari extension from the App Store, enter the CSS code in the extension and save the code. Now refresh youtube and it should work perfectly.

Credit and a big thank you to Gnattu over at MacRumours forum for the fix!

I'm also experiencing this on an M1 MacBook Air running Big Sur 11.0.1. My first thought was that this was intentional, because it's hard to believe they wouldn't have done testing on one of the most popular websites in the world. But it does seem to be a bug.

On YT's main page, scrolling is working fine for me, but in any video, scrolling seems 'sticky', like starting scrolling (in any direction) the page seems 'stuck' until enough 'scroll action' is input, then it becomes unstuck and glides. Once it stops, though, the same issue occurs.

It seems to be 'inertia'-based. Turning off inertia when scrolling breaks scrolling all-together on a video's page.

I find this occurs when the 'vertical elipsis' (three vertical dots) appears to show more comments are available.

If you scroll on the very left of the screen (to the left of the avatars) it seems to work smoothly.

This! Ive been having this issue as well. It doesnt scroll whether I'm using the trackpad or an external mouse. This has been driving me absolutely insane and making me seriously consider moving over to Chrome. :/

Been experiencing this for the last 2 weeks now, on Big Sur. This is extremely frustrating, hope a member on this thread can either post a solution to this issue or a link that has been plucked from the fringes of the internet.

This is the most annoying bug I've encountered in recent memory. Apple has to be aware of this, or providing a fix soon. Until then I guess I'll just keep moving the cursor to the left side of the page on YouTube in order to scroll.

I have the same problem here in Safari on a MBP 15" with macOS 11.0.1. Scrolling through the Youtube comments is very weird, although when I use the keyboard to scroll up or down, it works just fine. Restarting Safari/OS doesn't fix it.

Thank you for your solution.

I have exactly the same problem on Safari 14.0.1 on Mojave 10.14.6. My workaround was to use arrow keys but it's pain the rear end. Positioning cursor at the left edge of youtube window to the left of the avatars works around the bug really well. But I found the scrolling bug persists no matter if vertical ellipses is in view or not. As long as you are anywhere but at the left edge you can't scroll with two fingers. Hope this helps to clarify the workaround, and hope Apple fix this bug soon.

Once the extension is installed, you click on the extension in the toolbar of Safari, which will load up userscripts extension, then you create a new userscript and enter the text as per the screenshot I’ve added above previously. Hope this helps

Thanks, I will try this later on my macbook.

It seems my Safari version is too old on my mac mini (where the scrolling problem is worse). I can't update just Safari and I can't update my OS because I'm running music software that isn't compatible yet.

the exact same problem is present on my macbook pro with m1 processor ... when I scroll both on safari and on chrome the problem occurs .. especially if I do it quickly. It refreshes me not to be the only one

I believe the scrolling/web styling issue with Youtube is specific to Safari 14 (which is available for macOS 10.14-11.0. Not sure if it affects earlier versions of Safari, but I didn't notice it when I was using Safari 13. I think a fix will most probably have to be from Youtube, as the scrolling issue doesn't seem to affect other websites?

it happens to me more or less on every site ... it is clear that there are small clicks ... this does not happen on the programs ... but if I open heavier sites a little effort ... sites like the verge or amazon. .. scrolling down quickly you can see micro lagg

Hey I also have this problem only on the YouTube page. With the trackpad you can still scroll but I am also using a Mx Master for Mac mouse. With the mouse it even gets completely stuck. This means I can't scroll anymore at all. If someone has a solution please help me haha.
