Obvious sub 120 Hz scrolling with this site. <gnome.org>

This would have to be one of the more obvious examples of low frame rate scrolling. It looks like <60 Hz in Orion, probably around 30 Hz. Runs perfectly buttery smooth in Safari. Tried a new profile with compatibility mode; same result.

I've started using Orion again after more than a year of abandoning it. Honestly the improvements are great. 😀 I do know that Orion relies upon β webkit, which of course may be buggy, because it's pre-release. Most things are working well, but this site really stood out. I have noticed that this β webkit scrolling, is a lot more Chromium like. The current Safari (18.3) is very smooth, accelerates quickly ,and continues rolling with momentum. Whereas the newer Orion scrolling; seems less reliable in regards to buttery smoothness, and has more friction with rolling to a stop (A bit like an EV with one pedal driving mode on). Personally speaking, the new scrolling physics isn't a deal breaker (users can adjust to new things), but the low frame rate scrolling is unattractive and gives the impression of bugginess.

Does Vlad and the Orion team have any control over this behaviour, or is it baked in to β webkit?

Buttery smooth 120 Hz scrolling.

Yes, tried that.

Do you think that using such a bleeding edge build of Webkit causes these kinds of bugs?? Maybe it would be better to use a more 'production release' version of Webkit, as a solid base for your browser.

I've seen noticeable jank with Orion, on about half the open tabs. That buttery smooth scrolling in Safari has ruined me for other browsers!!

Could you go to https://www.testufo.com and see what it says?
do you have low power mode enabled? it may affect promotion

In Safari it displays READY 🟩, for 120 Hz. In Orion it's 'UNSUPPORTED:
Update Chrome to version 19+ for VSYNC support.' 🟥 The 120 fps is displayed however; I can't see any difference between Orion & Safari visually.

Macbook Pro is plugged in. Normally in Automatic, but I tried High Power. No difference.

I tried gnome.org again, and the jank is still noticeable in Orion.

This happens on the verge as well! On this verge article, [https://www.theverge.com/news/671514/google-ai-mode-overviews-ads-expansion], scrolling past a GIF makes the browser frame rate lag.

Framerate of the website should stay stable.
