The fix for the opengl child window rendering bug 2398 requires modern video
drivers support 'Redirected GL windows using' which requires Composite +
OpenGL. At the moment Nvidia supports this and the latest intel drivers and
some GIT versions of other drivers.

So if you are not using an nvidia card then that is the problem.
