Render glitches in 5.2

There seems to be a regression related to text rendering or item stacking. In some cases, text items are not visible for alternating rows in table view.

It can be reproduced on mac with the following example:

import QtQuick 2.2
import QtQuick.Controls 1.1

ApplicationWindow {
    NumberAnimation on width {from: 320 ; to: 350; running:true ; duration:1000}
    TableView{
        model: 100
        anchors.fill: parent
        TableViewColumn {}
        TableViewColumn {}
    }
}

Screenshot attached shows that the view incorrectly renders only alternating rows.
