QtQuick 2.0 TextEdit, TextArea, both are very-very slow on high-end PC

QML and Qt Quick
-
I have a very-very simple code:
import QtQuick 2.6 import QtQuick.Controls 1.5 import QtQuick.Dialogs 1.2 ApplicationWindow { visible: true width: 640 height: 480 title: qsTr("Hello World") menuBar: MenuBar { Menu { title: qsTr("File") MenuItem { text: qsTr("&Open") onTriggered: console.log("Open action triggered"); } MenuItem { text: qsTr("Exit") onTriggered: Qt.quit(); } } } TextArea { anchors.fill: parent } }
If I paste a file of 6000 lines in the TextArea it is works very-very slow and laggy. However, the text scrolls quite fast, the interacting with it (selecting, writing, deleting) works very-very and very slow and freezy.
What can I do to increase performance? For example, QPlainTextEdit in c++ works much better.Qt 5.6, Archlinux x64, i7 4790, 32gb ram.
