FNCDataGrid behavior in Win11 and Win10

FNC TMS FNC UI Pack

I've an application using FNCDataGrid. In Win11 OS eveything work fine. Cell scrolling is smooth and stable. In Win10 during scrolling cells flicker and refresh unsteadily. DoubleBuffered is set to True. What should I pay attention to? I'd be grateful for any hint. I'm working with latest version 6.5.0.1 on Delphi 11.3 VCL.

Are you working on a Virtual Machine or Remote Desktop?

On Remote Desktop. Indeed, right on computer everything is ok. Thanks a lot for your tip. By the way, is there any way to make stable cell scrolling on Remote Desktop?

It's not related to the data grid or any other double buffered component, but actually to VCL running on a remote desktop. There is actually a property to fix that

https://docwiki.embarcadero.com/Libraries/Athens/en/Vcl.Forms.TApplication.SingleBufferingInRemoteSessions

program Project1;

uses
  Vcl.Forms,
  Unit1 in 'Unit1.pas' {Form1};

{$R *.res}

begin
  Application.SingleBufferingInRemoteSessions := False;
  Application.Initialize;
  Application.MainFormOnTaskbar := True;
  Application.CreateForm(TForm1, Form1);
  Application.Run;
end.
