Hi all I'm gonna add my 5 cents on this topic. I was having similar problems in app which recreates viewer in runtime (there are preview window and viewer created when widget shows up), using osg version 3.0(?). In my case problem was not only with textures - i was getting corrupted vertex arrays after viewer re-creation. I tried some voodoo magic with osgDB::Registry and caching settings, tried to clear gl objects with osg::deleteAllGLObjects() osg::flushAllDeletedGLObjects() etc, but without any luck. I've had different graphics context ids after viewer recreation. In my case problem was solved when using vertex buffer objects instead of display lists, i didnt dig any further after that. IIRC problem was showing itself only on windows, but i cant say for sure now.
