Scrolling a SfDataGrid is much slower after version 21.2.4

I've been updating my Syncfusion libraries, because some of my feedback has been integrated, but since then our application is very slow when scrolling.

The problem seems to appear for all builds after 21.2.4.

It's even apparent with only ~20-30 rows, ~10 templated columns and 1 level of detail grid.

The scrolling will come to a halt for up to 3 seconds, when the detail grids are expanded.

Profiling shows that most of the time is used in WinUI Layouting and Syncfusion code.


We will probably reduce our number of columns and use standard text columns, where possible in the future, but the harsh differences between release 21.2.4 and later would suggest, that you implemented something for the later releases that doesn't scale very well.
