Hi, sorry for long delay My system is Ubuntu 14.04 Nvidia GTX970 346.47 drivers I use latest osg from git and patch it with your patch. I tested with OPENGL_PROFILE=GL2 and OPENGL_PROFILE=GL3 same result Also I installed graphics degugger from here http://www.gremedy.com/ I attach my test scenario and logs from gremedy so please pay attention on lines 21-52 OSG creates two VAO but binds two EBO to VAO1 and in VAO2 there is no EBO but according to specs if you want to draw with VAO you have to bind it to every VAO so after line 148 OSG binds first VAO and drwa it but after it binds second VAO and now there is no EBO binded so nvidia driver dont know about EBO and hangs up. I suppose you test it in windows so if windows driver behaves this way it's not right accordings OpenGL specs. Thank you!
