    Hi,<br>
    <br>
    I'm using the archlinux build of VTK, so the OpenGL2 backend should
    be disabled and the QT version is at 4.8.7.<br>
    I've attached the svg as displayed on my machine. I'll try the demo
    on Ubuntu tomorrow, to ensure that it's<br>
    an issue on my machine only.<br>
    <br>

                        <br>
                        I'm trying to export an image from my
                        application created in PyQt4 to a<br>
                        vector image. While the vtkGL2PSExporter works
                        fine from outside my QT<br>
                        application, when trying to export the image
                        from inside it the output looks corrupted. A
                        minimal example can be found at the end of this
                        email. Did I miss something (or call something
                        incorrectly)? Is this a known issue?<br>
