Created attachment 464848 [details] weird temporarily artifacts Happens in both WebKit (6c4c9810) and Safari 16.2, 1. Open https://codepen.io/jh3y/pen/VwBgPxP 2. Scroll down and up, fast and slowly, like what is shown in the attachment. Actual: Weird artifacts will be seen sometimes specially when top overscroll happens. Expected: Like Chrome and Firefox I saw this codepen from this tweet, https://twitter.com/jh3yy/status/1621564942175322112

Created attachment 464849 [details] Artifacts Something similar also happen while scrolling of https://meodai.github.io/poline/ only in Safari and not Chrome and Firefox on an M1 MacBook Pro.

Created attachment 464851 [details] resize and scroll I wasn't able to reproduce it but resizing the content frame makes the gallery move off center while it jumps right back soon after I star scrolling -(which looks very similar to what the attached "artifact" recording shows with the misplaced content). Firefox seems to always center the content.

I no longer see much an issue here. Guess some driver or graphic layer fixes has happened which is great. Thanks
