Demo flickers on page scroll

[cjcheshire]

Hey, just stumbled on your library (via Sid mailing list). Looks slick 🙌

I spotted on the demo site it seems to not like the browser page scrolling? It results in a nasty flicker and a times no longer paints the list.

Device is an iPhone X, iOS 12.2. Suspect you could replicate on other iOS devices.

Thanks! 👍 I believe I introduced this regression recently; Seems specific to iOS. It's in my TODO list.

No worries, I hate to bring problems without solutions :)

Fixed in v0.7.0. Had to rework the positioning mechanism for that.

Hi @petyosi , There's still a screen glitch in iOS, it happened when scroll back to top, when near the top it will glitch - before the spring from top occurs, I'm using material ui navigation drawer on the left (if there's conflict)

Thanks

@x4080 can you reproduce that on the examples? If not, can you fork one of them to Stackblitz and showcase it? I will take a look.

@petyosi I'll try it and let you know

@petyosi I havent tried using the examples, but when I take a look at the flicker, that happened outside of the virtuoso, I'm using material ui appbar, and inside paper component I put virtuoso and the flicker is in app bar when reaching near top of list and bouncing effect from safari is started

I have to see that in order to help you. Please try replicating it in a sample (stackblitz or code sandbox). Cheers!
