<div><br>It causes the volume rendering test [0] to fail [1] with the following error:<br> <br><pre>Generic Warning: In /home/kitware/Dashboards/Nightly/Slicer-0-build/VTKv6/Rendering/Context2D/vtkContextDevice2D.cxx, line 27
Error: no override found for 'vtkContextDevice2D'.</pre>This has already been discussed few days ago in [2] but we didn't came to a solution.<br></div><br></div><div>I suspect it is related to the recent work done regarding the support of different rendering backend.<br>
<br></div>Any idea what could be done to fix this ?<br><br></div><div>You will also find below a complete backtrace.
