Created attachment 440743 [details] a screencast It is similar to bug : https://bugs.webkit.org/show_bug.cgi?id=197660 However this one occurs in Safari 15 with a Mac(Intel). Example URL: https://x80lf.csb.app Steps to reproduce: 1. Open attached url 2. Scroll vertically What is the expected behaviour? The fixed purple cell should remain in the same position when scrolling. What went wrong? The fixed purple cell is jumpy and disappears and then reappears while scrolling fast with the mouse wheel. If you remove position:sticky from the outside container, then it works as expected.

I think this might be a duplicate of bug 199915. Can you confirm whether or not this is failing with Safari Technology Preview (https://developer.apple.com/safari/technology-preview/)? Thanks!

I've tested this, so I'm marking it as a duplicate, but if this is still failing I can reopen the issue. *** This bug has been marked as a duplicate of bug 199915 ***
