Dear vtkusers,

When using vtkOpenGLVolumeTextureMapper2D to render a volume I get a 
white image with DRI enabled. Without DRI the image is correct although 
very slow.
The Mesa opengl demos do work with DRI enabled. So it looks like a 
problem with the texture mapper. 
I've read several messages about problems with texture mapping and DRI 
but none with the same problem.

Anyone some suggestions ?

I'm using vtk 4.0 (or 4.1 I don't know how to check that)
xserver-xfree86 4.1.0-16, kernel 2.4.18, debian woody, mga.o and 
mga_dri.so from Matrox.


Thanks,


Larry
