When references a 3rd party code that is online somewhere it would be worth
providing a link to it.

FYI, osgWidget is a NodeKit in OSG-3.4 so references a class of the same
name is a bit confusing.  I presume you aren't talking about the osgWidget
NodeKit as it has nothing to do with Qt.

As the issue, is this a new issue?  Could it be lack of depth testing?
