In the PVRTraceGUI that comes with SDK 2016 R1.2, I’ve noticed that in the OpenGL ES State tracking tab the GL_VERTEX_ATTRIB_ARRAY_ENABLED flag seems to be false for all attributes.

However, the scene is rendering properly, and if I search back in the same frame for (Enable|Disable)VertexAttribArray, I find that vertex attribute arrays 0,1,2,3 are all enabled, as expected.

If you need me to provide a trace, just let me know. This is dumping an app captured under the ES3 profile, and these draw calls are rendering from VBO.
