Hello

These black rectangles are shown when but size of the control is changed, background is not rendered yet.

Extended borders solves this issue.

[Lasse]

I managed to solve this when not using extended borders mode:

Code:

procedure TBaseForm.FormCreate(Sender: TObject);
begin
inherited;

SetClassLong(Handle, GCL_HBRBACKGROUND, GetSysColorBrush(COLOR_WINDOW));
end;

Thank you, I didn't knew this feature.
