> The recent fixes for PIVOT-474 revealed what appears to be an issue with the scroll pane
optimization. The prior repaint logic when the selection state changed in ListView and TableView
was incorrect, causing a larger area to be repainted than necessary. Now, artifacts appear
as the user navigates a list view or table view whose rows are partially obscured. This is
visible in the Tables section of the Kitchen Sink app - select row 5 in the Sortable table
example and press the down arrow several times.
> Turning off the scroll pane optimization resolves the issue - however, that is obviously
not ideal. Another possible short-term workaround is to repaint the entire component when
the selection changes in a list view or table view. This is also not ideal but may suffice
until a more complete fix can be applied.
