One thing to check is to make sure are loading your textures again when you come back. I use GLSurfaceView, so any EGL stuff is handled for me, but I know I have to load textures again in GLSurfaceView.Renderer#onSurfaceChanged, not GLSurfaceView.Renderer#onSurfaceCreated, which is called less often. Otherwise I get similar problems. That's sort of similar to your situation.
