We appreciate your report but I was not able to reproduce this issue. I was able to scroll correctly in page:

It needs to be scrolled as fast and pressed as possible and scroll up and down very quickly at the side and top and bottom of the site. Can you test directly from your phone? (without console, etc). And try to make the toolbar visible as well. I see this behavior on all sites.

@claudiu64 Not quite sure I understand the updated steps to reproduce.

It needs to be scrolled as fast and pressed as possible

could you please elaborate on the "as possible" part?

at the side

could you also elaborate on this? Side-scrolling is not possible

@softvision-raul-bucata
Well the idea is to scroll the site very fast scrolling, up and down, right in the area where the site ends. You can also zoom in on the site and scroll even in the same zine, at the end of the site, and you will see in more detail how the text shakes.

[claudiu64]

Also test with a 60fps phone, not 120fps or higher, to try to reproduce the main bug as well.

[softvision-raul-bucata]

@claudiu64 Please provide a way to check the maximum FPS of an Android phone.
