DataGrid: Flicker when using templates and dynamic update

Flicker can be observed when datagrid is manipulated/updated, or entering in edit mode. One example is tapping on a column header - when there is a column with a HeadetTemplate, the column header flickers. Other example is to double-tap a cell to go in edit mode. Also the behavior can be reproduced when DataGrid TemplateColumn is used.

Hello Alexander,

Thank you for your input on this issue.

Indeed, the flicker can be observed only with DatGridTemplatedColumn when data is refreshed. 

Please follow the feedback item to get notified as soon as there's any progress on it.

To add on to this, refreshing the ItemsSource causes the flickering as well. 

DataGridTextColumn does not flicker from what I can tell, but DataGridTemplateColumn does as well as a custom made column type.  Not entirely sure if this is related to rendering speed or not.
