Hi Jim,

Could you be forgetting to QSGNode::markDirty() the node when you change it, by any chance? 

cheers,
Gunnar

This has been working perfectly well on Qt 5.0, but trying the exact same code does not work correctly on Qt 5.2. On 5.2, I only see anything get rendered when I create some kind of event in my QML application, such as clicking/tapping on my app window while video playback is occurring. And when I do that, I only get 1 frame per click/tap. My question is, why would this be occurring on 5.2 and is there some fundamental change in 5.2 that I need to take into account?
