alt Hacker News> disagree with the theory that scrolling frame rate doesn't need to be smooth for scrolling to feel smooth
It's possible you might be misunderstanding what I was trying to say here because 120hz scrolling on a 120hz device was the goal and why one of those virtualization techniques was not acceptable to me which lead me to coming up with a novel workaround to this problem (Inverse Sticky Technique).
CodeView uses a system that allows scrolling to update at your native framerate (120hz) WITHOUT needing Javascript needing to keep up at 120hz. If you're seeing stuttering while scrolling on https://diffshub.com would love to know more context (device/diff link/etc) because that is very much NOT our experience.
Even the linked ghostty PR on your home shows this - this is Firefox Android on a Nokia XR21 / TA-1486.
It's not unuseable, but it definitely feels like 'js hacking my scrolling' and not a native surface flinging around.
The experience is actually worse with smaller movements, i guess because my brain is more conscious when breaking the 'finger physically moving the text' illusion.
I don't mean to be dismissive - you're working on a really hard problem, and you're clearly approaching it with a mindset of perfection. I'm posting because I know you're probably able to solve this too :)
Edit: as a point of (unfair) comparison, the codemirror Huge File demo works fine: https://codemirror.net/examples/million/ It does suffer from the occasional partial paint when quickly coasting, but I'm not bothered by this at all, it's far less intrusive than dropping frames / stuttering / etc.
