Wow, yeah this is very bad. As far as I can tell it’s not directly flexbox related, because if I remove flexbox from the container it still happens. Definitely seems to be _yet another_ Safari rendering bug. There are some _similar_ iOS Safari bugs that can be fixed by adding `-webkit-transform: translatez(0);` to the CSS of the fixed container… and it looks like that fix works for me here too. Generally not regarded as a great option, as it apparently forces GPU acceleration so it could impact performance. I can only reproduce it when creating a new topic… so there must be something unique going on there. Investigating a bit more… --- _[View the full topic](https://meta.discourse.org/t/flexbox-vertical-scrolling-issue-on-macos-in-safari-11/73797)._
