[vbox-dev] OpenGL/3D on Mac Hosts... Screenshots

[Louis King Jr]

Some further info, if I try to take a screenshot from the VirtualBox menu,
i.e. Take Screenshot (Host + E), even with Debian 7 I don't get a correct
screenshot. It only shows the wallpaper. Screenshots work fine from within
the guest.
