Alright, I've been chasing this down since I was able to get my libraries straight. I'm currently working on the Qt/OSG application previously discussed. The system uses a QOpenGLWidget with an osgViewer::GraphicWindowEmbedded .
To simply things I have created a QWidget that inherits from QOpenGLWidget. It contains a osgViewer::CompositeViewer. The scene is defined as a Ortho2D. It contains 4 sphere's 2 Along each Axis They have a radius of 1/4th the view dimensions. For debugging every call to update() in Qt the camera node's clear color is adjusted. On Windows and Linux I see the scene as I would expect, but on Linux I simply get the oscillating clear color. Because the background color changes appropriately with each new frame. I know OSG is operating in the right GLES context and the buffers are properly swapped by Qt, but I can't explain what could cause the objects in the scene to be skipped or drawn off screen. I can post the class if anyone is interested it is fairly small, but I would be very interested in hearing others debugging techniques on multiplatform applications or experience working with OSG on android.
