Hi David, The issue looks likely to be totally un-related to the bug in Ale's program revealed by the bug fix to OSG-3.2. There is chance that your own application has this bug in the setup if you are applying your own osg::Camera to a View(er) without setting up state correctly, but as this is niche usage of the OSG it's likely the issue you have is unrelated. It may be worth double checking this though.
>From your code snippet and warning report it's not possible to guess what might be wrong. It could be a bug in your app, your particular build, the OSG or OpenGL driver. Which is the culprit isn't possible to say at this point. Could you create a small code example that reproduces the problem so that others can recreate the problem? Robert.
