    <p>I also noticed this when playing with the netrender, seems to be

                            i have successfully managed to build the

                            dependencies from .../lib/win64_vc14 with
                            vs2015 express and vs2017 express.<br>
                            but when i render an example scene i get
                            only the upper right quarter of the image
                            render right. the rest of the image is
                            blueish...see attached image.<br>
                            dont know why...is this a source code bug or
                            a build bug?<br>
                            does anybody also have this strange
