I have a vaadin11 grid with multiselection and about 4000 entries.
The scrolling work quite well if nothing is selected.
The selection of all entries takes very long and the scoll-performance is very bad.
I’ve also been meaning to file a bug on this. It’s also an issue in V8 and you can duplicate it by clicking the “select all” check. Doing this with a Grid containing 250k rows will lock up the session for 15+ minutes.
Chris, if you’ve filed a bug, would you mind linking here?
