    Description

      The WebEngineView component seems to be unstable and crashes easily and frequently. This occurs on version 5.13.0 and the crashes don't occur if I switch to version 5.11.3. It doesn't seem to matter what web page I try. I've tried both local html files and remote sites, like google. It can easily be reproduced with a fresh project in qt creator. The crash itself is seemingly random.

      Steps to reproduce:

      • In Qt Creator, create a "Qt Quick Application - Empty"
      • Import QtWebEngine 1.7 at the top of main.qml and add a WebEngineView component inside the Window component, like so: 
        import QtQuick 2.11
import QtQuick.Window 2.11
import QtWebEngine 1.7

Window {
    visible: true
    width: 640
    height: 480
    title: qsTr("Hello World")

    WebEngineView {
        anchors.fill: parent
        url: "https://www.google.com"
    }
}
      • when the web page loads, navigate and interact with the page normally, as a user would. (mouse clicks, hovers, scrolling, etc.)
      • at some point, the page will freeze, crash, and disappear.
