Research direction

Start by reproducing the issue with any WPF UI DataGrid on Windows 11 using WPF-UI 4.0.2 and .NET 9.0.300. Trace the DataGrid scrolling behavior to locate the relevant control or scrolling entry point. Done means scrolling moves smoothly and pixel by pixel rather than in visible jumps.
