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>

<div>1) What Qt version are you using, and</div>
<div>2) Which OpenGL backend is being used on VTK? (Did
you explicitly select the experimental OpenGL2 backend

<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>
<br>
Version: VTK 6.1.0<br>
<br>
Thanks for any help,<br>
