On the host the 3D content is rendered to a host<br>window - a separate one from the normal guest screen window, which<br>sometimes causes unwanted artefacts when 2D and 3D guest rendering are<br>mixed.<br><br>It will probably take you a while to get used to our build system to<br>work out what goes into libGL.so (including generated files), but you<br>will probably have to go through that.<br><br>Hope that helps for a start.<br><br>Regards<br>Michael<br>-- <br>Michael Thayer | VirtualBox engineer<br>ORACLE Deutschland B.V. & Co.
