Yup, but I won't move because I want a free open source native application, any idea what could be causing it ?

It lags even in comments tho, for example I will scroll to the bottom of a 20 comment feed and back up and its still jitters and lags a bit, justnot smooth, bird app in contrast feels much smoother. All my other apps have a smooth scrolling experience, is there not a way to fix it?

Thats fair enough, its still usable and doesn't crash like another app I use with a blue bird logo every 30 mins
