For years there have been rants about flicker in Vcl applications. So when I tried to fast resize a form with an EdgeBrowser and saw the browser scrollbar jumping right and left, I assumed that it is Delphi's problem. Then I tried the same with Edge and the result was the same. Massive flicker when the scrollbar is visible! Bravo Microsoft! In fact Edge flickers even without scrollbars, whilst Delphi's EdgeBrowser doesn't.
By the way does anyone know how to Vcl style the EdgeBrowser scrollbar?
