ADDITIONAL INFORMATION

Removing `default property alias delegate: root._delegateComponent` from CardsGridView.qml fixes the problem

Comment 1 Emmanuel Lepage Vallée 2018-12-11 11:00:49 UTC

Apparently this can be mitigated using `model.roleName` instead of `roleName`. Still, it should be a drop-in replacement so it is still a bug.

Sadly, DelegateRecycler has to be used because ``ActionsToolBar`` has problems without using it. Try using CardsGridView without DelegateRecycler and try scrolling up and down really fast (you have to have a model of more than 50 items).
