[vtk-developers] Performance slow down

[Mathieu Coursolle]

Hi,

I've track down the source of the problem to this change:

http://public.kitware.com/cgi-bin/viewcvs.cgi/Rendering/vtkOpenGLDisplayListPainter.cxx?r1=1.7&r2=1.8

For some reason, if I undo this single change, it is rendering as fast  
as before.

Anybody knows what the problem might be?

Thanks!

Mathieu
