HI Alexis, This looks like an issue with your application setting up the viewer Camera's without initializing the Camera's StateSet to global defaults. 3.0.x and 3.1.x have a bug where the internal rendering setup overrides the Camera's StateSet forcing the global defaults so would hide where this wasn't done correctly so in effect hid this bug in client applications.
In OSG-3.2.x If you use osgViewer::View(er)'s default Camera it will by default set the the StateSet global defaults that you can then override if you wish, but if you apply your own osg::Camera in place of this it won't have the StateSet's set up with global defaults and will just what you set it up with, and if you don't provide any then it'll be just OpenGL defaults which won't enable key things like depth test. The simple solution is to reuse the View(er) Camera rather than replacing it, or if you do replace it call StateSet::setGlobalDefaults() on the Camera StateSet that you are applying. Robert.
