After using the DialogHost. Show() method, if multiple rows (over 10000 rows) are selected in the DataGrid, it will seriously affect the rendering speed of the UI. At present, I have found this issue on many computers. If the DataGrid data exceeds tens of thousands of rows, when performing a select all operation, the UI may even lag for more than ten seconds. The same amount of data results in a fast rendering speed before using the DialogHost. Show() method. Visual Studio performance probe analysis was used and it was found that the stuck time was used for GC.

@fzhxhdd888 are you able to provide a sample of your setup? Is the DataGrid inside of the DialogHost? Do you have virtualization enabled on the DataGrid?
The above link is a small case study. Currently, I have tried many computers with this issue. There are also a small number of computers that have no issues, so I am very confused.
