问题：dcef3 for Firemonkey 浏览器控件，拉动窗体大小会闪烁的问题
修改源码：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(, , b.Width, b.Height), RectF(, , b.Width, b.Height), , True);
FBuffer.Canvas.EndScene;
b.Free;
end;
brws.Host.WasResized;
end;
end;
end;

注：dcef3 FMX 用 Bitmap 处理，效能不如 VCL 的好，还是建议使用 VCL
