This happens to me only in calendar, and for the first couple of swipes. If I open the calendar and want to advance a couple of days, it usually jumps back a week, then another week on the second swipe (yes, while i swipe up). Usually by the third or fourth swipe it is back in line, then I hit the today button, and all is good.
I'm alone with this problem ?
How I can install a clean 18.104.22.168 without flick scrolling ?
