問題：dcef3 for Firemonkey 浏覽器控件，拉動窗體大小會閃爍的問題

修改源碼：ceffmx.pas

找到 procedure TCustomChromiumFMX.Resize;

修改如下：

procedure TCustomChromiumFMX.Resize;
var
  brws: ICefBrowser;
  b: TBitmap;
begin
  inherited;
  if not (csDesigning in ComponentState) then
  begin
    brws := FBrowser;
    if (brws <> nil) then
    begin
      if FBuffer = nil then
        FBuffer := TBitmap.Create(Trunc(Width), Trunc(Height)) else
      begin
        b := TBitmap.Create;
        b.Assign(FBuffer);
        FBuffer.SetSize(Trunc(Width), Trunc(Height));
        FBuffer.Canvas.BeginScene;
        FBuffer.Canvas.DrawBitmap(B, RectF(0, 0, b.Width, b.Height), RectF(0, 0, b.Width, b.Height), 1, True);
        FBuffer.Canvas.EndScene;
        b.Free;
      end;
      brws.Host.WasResized;
    end;
  end;
end;

注：dcef3 FMX 用 Bitmap 處理，效能不如 VCL 的好，還是建議使用 VCL
