LazyColumn gets stuck scrolling when an item is too big. #800

Closed Dominaezzz closed 3 years ago

Dominaezzz commented 3 years ago

I haven't isolated a reproducer for this yet but when the size of an item in the LazyColumn is really close to size of the LazyColumn itself, the scrollbar keeps snapping back, preventing further scrolling. To escape this, I have to scrolll very aggressively, or fast enough to beat the snap.

Fix 0.5.0........

Sorry this has nothing to do with srollbar. LazyColumn does this by itself.
