Butter smooth for me. Samsung s21 here and Samsung galaxy Tab s8 plus. Lemmy jerboa is silk.

And also alpha, lot of more bugs. Maybe in future releases get better, for me the website is best option for now

I have the same issue. It’s worse when the header is sliding in and out, but I have no idea what causes it. It’s not unusable though, just a bit laggy.

This has been a problem since forever. But it’s much better now.
