WebEngine memory leak while in youtube?

Izba

Hi all,

I'm trying to add Youtube view in my softaware and i started noticing lagging, so i checked the taskmanager and saw that something was eating all my ram.

I made conclusion it had something to do with WebEngine cause the ram started to get eaten when i started a video. I also made another test to make just a simple QtQuick app with only WebEngine in it with youtube as url and after clicking a video something started eating my ram again step by step until there was no ram left.

//main.cpp
#include <QGuiApplication>
#include <QQmlApplicationEngine>
#include <QtWebEngine>
int main(int argc, char *argv[])
{
    QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);

    QGuiApplication app(argc, argv);
    QtWebEngine::initialize();
    QQmlApplicationEngine engine;
    engine.load(QUrl(QStringLiteral("qrc:/main.qml")));
    if (engine.rootObjects().isEmpty())
        return -1;

    return app.exec();
}

//main.qml
import QtQuick 2.9
import QtQuick.Window 2.2
import QtWebEngine 1.5
Window {
    visible: true
    width: 640
    height: 480
    title: qsTr("Hello World")
    WebEngineView{
        anchors.fill: parent;
        id:youtube;
        url: "http://www.youtube.com";
    }
}

Should i file a bug report or am i just doing something wrong here? I'm building this as Qt_5_10_1_MSVC2015_32bit.

Thanks in advance,
Izba
