Yeah, there's a bug in the intel drivers that give
us the wrong gl uniform ID when we try to look up
a shader variable.  I think we had a hack around it,
but it just exposed another bug.

Someday I hope to fix Mesa.. never seem to find
the time.  We've notified intel about the windows
driver bug, but a while ago and it doesn't seem to
be getting looked at...

Sorry.  Stick to nvidia on linux for now, or
nvidia/ati on windows.  Mac's driver actually plays
well with intel cards, as I remember, FWIW...

----- Original message -----

I've recently acquired a Lenovo X220 laptop with the new IntelHD 
integrated graphics processor.   ImageVis3D runs, but after loading data 
set the render window remains blank, just an empty black window.   If I 
turn on local or global outlines I see the rectangles drawn around the 
missing render data and these rotate just as if the program was working 
properly.

If I start the program from the command line in Ubuntu 11.4, the 
following errors are listed:

Mesa: User error: GL_INVALID_OPERATION in glUniform(type mismatch)

When using other volume rendering software that relies on openGL 
hardware support, the rendering occurs normally.   I've tested the system 
using GL_gears which operates normally. I see a similar problem when 
running iv3d under Win7.

All OS's are 64 bit and in the case of the linux version, I've 
downloaded the latest svn version and locally compiled, all without
success.

Any help would be greatly appreciated.
