Window flickers when resized on OS X

Details

    • macOS

    Description

      With a very simple scene (a Rectangle in a Window), resizing the window causes grey/unpainted junk to appear on the right and bottom edges. This does not occur when "QSG_RENDER_LOOP=basic" is set in the environment.

      See the attached image and video.

      The code is:

      windowTest.qml
      import QtQuick 2.5
import QtQuick.Window 2.2

Window {
    id: window
    visible: true

    Rectangle {
        anchors.fill: parent
        color: "black"
    }
}

      Then run it with qmlscene.

      The Window could be replaced with Item instead. Same issue.
