the vertical scroll animation, especially once the cards go behind the stack

oh, you mean the video itself lags, not something you experience in the app?

the app in your video does, that's my point

got it. yeah, promotion-Sebastian should have taken a little more time to get this right :) Unfortunately, development-Sebastian took back control too soon

as long it doesn't actually feel laggy when using and renders at [insert phones frame rate] it's fine, it just looks silly

Yeah, I just checked the original and it's way smoother. Seems like the tool I used to frame it cuts down the frame rate :(
