You want to invert the logic on line #L287 of GL4RenderSystem and use
        if (!canvas.getAutoSwapBufferMode())
so that your buffers will get swapped when you have disabled automatic buffer swapping.

After fixing that you can remove all the workaround swap logic from GenericSceneManager
Remove lines 517-522.
