When a TreeDataGrid uses a TemplateColumn with a binding to a Task that returns a string the display is flickering when the underlaying Collection has a reset event.
In comparison a DataGrid view does not show such an issue.
There is no flickering if the TreeDataGrid is noch bound to a Task.
I would expect no flickerung if there is no reason because of the actual execution time of the task. I would expect to get a similar visual experience that the DataGrid offers.
