Dawn shows 205 comments total so it's not that large, but scroll lags and you can see stuttering when kinetic scroll is triggered so I think it somehow depends on the whole thread size and on count if currently visible comments.
My device is zte a2017g (android 9, snap 820, adreno 530, 1440x2560)
This may also depend on specs so needs more testing and affected threads
Scrolls smoothly on htc m8 (android 10, snap 801, fhd). Maybe because of lower res (unlikely, but still), or different rom. Might worth to try with android 9 rom
