Hi,
Why are you re-creating the texture on every node update? Does the
m_Renderer->getImage() really changes? My first guess would be that the
texture creation from image is the most costly part here (uploading the
texture to GPU?) and I would do this only if necessary (the image really
changes).
You mean QML or QtQuick? If you want to instantiate widgets from QML then I
think this should not be a problem (as you can instatiate there any
QObject), just expose them to QML engine. If you mean embedding QWidget in
a QtQuick application, then Olivier gave you the answer.

First of all you need to decide which QPA plugin you want to use. If you
use Ubuntu on the device then I guess you want to launch your apps in X11,
right (like on desktop)? Then xcb plugin is what you need, so passing
