Black windows on Nvidia Jetson TX1 board (Tegra X1)

I compiled Qt 5.6 on the Nvidia Tegra X1 board. When I try to run a QML application, the window appears black. No error message is shown.

To reproduce this issue, just create a colored Rectangle in QML:

import QtQuick 2.0

Rectangle {
    width: 100
    height: 100
    color: "red"
}

When you load this file in the qmlscene application a black window occures. Using Qt 5.5.1 on the same platform, the correct red rectangle becomes visible.

The reported behavior occures with the xcb and the eglfs plugin. Other plugins couldn't be tested.
