@burnout426 "is really choppy in both Chrome and Opera" hmmm, weird, to me, in Chrome, it's smooth on "top level" (no choppy). Even more smooth in Mozilla, have nice scrolling display.
"I'm guessing it's an issue with Chromium", i don't know much about that, but maybe.
Thanks for did that and update. -

I'm trying the suggested "Smooth Scrolling" extension at the moment; can't quite tell yet if it's fixed it or not; scrolling still feels low framerate, if perhaps not quite as jerky when decelerating.
EDIT: After loading the "Opera" profile and testing out further, it definitely improves scrolling a lot in Opera. It's still a low framerate, meaning there's some ghosting (can't measure, but am guessing ~20fps), but it feels a lot smoother. What a pity Opera can't have something like this by default.

My monitor is a 1920x1080 display, not sure if it qualifies as "high DPI", since it isn't 4K, but I do have to go into a lot of older programs and set compatibility settings to override DPI scaling behaviour and set it to "scaling performed by: Application", to avoid them being blurry.
What difference should hardware acceleration make to scrolling? I have it enabled, but I've got 2017/2018 high-end laptop hardware. Opera should perform better by default than it does.

Scrolling seems normal here, at least using a mouse.
From my day-to-day usage, scrolling with a desktop mouse feels normal, it's only with a touchpad that I've noticed "low framerate"/jerky scrolling.

Further issue: sideways scrolling is not responsive at all. e.g. pinch to zoom, then try and scroll around horizontally/diagonally with two fingers. Compare performance between Opera and Microsoft Edge. Edge performs this function much better, though Opera is otherwise the better browser. In Opera, two-fingered horizontal/diagonal scrolling is very hit-or-miss, usually not working at all.

After further testing, the smooth scrolling extension seems to have made minimal/no difference to the low framerate jerky scrolling, making it worse on occasion... After disabling it, scrolling went back to a more steady, but still <10fps scrolling, though now seemingly more responsive to diagonal/sideways scrolling.
I wish to submit that this low-framerate scrolling with touchpads/Windows Precision touchpads is a bug in Opera. -

when opening that page https://www.sapsalis.gr/ and then opening Opera's task manager it shows that even when not scrolling the page is eating up inordinate amounts of CPU time and the memory usage continuously climbs and scrolling is also really bad here too using a mouse it feels like adsl days of 2~4Mb speeds not the Gigabit speed I have and it's just jerky jerk jerk all the way down the page

Thank you, @burnout426 for linking the bug report website; I didn't know where it was. I have submitted a bug report just now.

This is really weird... I was on O_55.something (the version where you fixed that "New Tab Omnibox not focused" bug), then this afternoon, I updated to O_55.0.2994.61, and scrolling feels a lot better... Not sure if it's fixed yet or not. Will keep y'all posted.

Has anyone else noticed smoother touchpad scrolling since updating to version 55.0.2994.61? Using Opera the past couple of days, and scrolling with the touchpad feels a lot nicer in general.

@darthagnon In this page sapsalis.gr, the scrolling is really heavy. I don't know why. Chrome and Mozilla it's good.

Reading the topic may help sometimes.

Thank you for posting that website; the scrolling issue can be reliably reproduced on that page. The problem is not solved, and still exists in Opera 56. I feel that on some sites that I was visiting, it may have improved slightly, but overall, scrolling is still jerky and unresponsive in Opera as of the latest version of O56. Please visit the posted site sapsalis.gr (Greek meme site or something) and attempt scrolling, pinching-to-zoom, and diagonal and horizontal scrolling using a touchpad on a Windows laptop to reliably reproduce the problem.
