So, i already posted on the old feedback page, but the reason of the lag when scrolling up and down the page is that they seem to be applying shadows on every element of the page.
On their ec9cb5e284c86ffe.css, there is this section:
*,
:after,
:before {
--tw-border-spacing-x:0;
--tw-border-spacing-y:0;
--tw-translate-x:0;
--tw-translate-y:0;
--tw-rotate:0;
--tw-skew-x:0;
--tw-skew-y:0;
--tw-scale-x:1;
--tw-scale-y:1;
--tw-pan-x: ;
--tw-pan-y: ;
--tw-pinch-zoom: ;
--tw-scroll-snap-strictness:proximity;
--tw-gradient-from-position: ;
--tw-gradient-via-position: ;
--tw-gradient-to-position: ;
--tw-ordinal: ;
--tw-slashed-zero: ;
--tw-numeric-figure: ;
--tw-numeric-spacing: ;
--tw-numeric-fraction: ;
--tw-ring-inset: ;
--tw-ring-offset-width:0px;
--tw-ring-offset-color:#fff;
--tw-ring-color:rgba(59,130,246,.5);
--tw-ring-offset-shadow:0 0 #0000;
--tw-ring-shadow:0 0 #0000;
--tw-shadow:0 0 #0000;
--tw-shadow-colored:0 0 #0000;
--tw-blur: ;
--tw-brightness: ;
--tw-contrast: ;
--tw-grayscale: ;
--tw-hue-rotate: ;
--tw-invert: ;
--tw-saturate: ;
--tw-sepia: ;
--tw-drop-shadow: ;
--tw-backdrop-blur: ;
--tw-backdrop-brightness: ;
--tw-backdrop-contrast: ;
--tw-backdrop-grayscale: ;
--tw-backdrop-hue-rotate: ;
--tw-backdrop-invert: ;
--tw-backdrop-opacity: ;
--tw-backdrop-saturate: ;
--tw-backdrop-sepia:
}
If you remove that whole section or even just the lines that apply shadows, you will get a huge performance boost.
