Hi everyone,
I know there has been a lot of discussions lately about ScrollSmoother and iOS/Safari, but I still could not find a solution to my problem.
I only see this happening on iOS 15.4.1 on Safari.
To see this effect you need to run the pen in debug mode.
When you touch down on the screen and start scrolling (with your finger down) really fast beyond the top of the viewport (basically to the very top of the url bar), the whole content disappears and reappears only when releasing your finger.
On the page I am developing this effect is even worse with the menu bar jumping wildly around, but you can see the effect in the pen as well, although I only included the bare minimum to reproduce the effect.
Edit: This behaviour goes away when I disable normalize scroll. However, I actually like what the flag offers. Thinking about disabling it based on device detection, but this is never a stable solution since I do not know which devices would have that problem.
