Hi, Guys
Big Thanks for testing. And Very Big Thanks to Ruben for this workaround.
Yes it also works for me. I am glad I started this thread before trying to
dig deeper in the OSG. Thats definitely something with drivers. I am not
sure if I will be able to quickly prepare pure GL test case quickly, though.
Sebastian: Just out of curiosity where do you send or post OpenGL bugs ?
Thru Registered developer's site or NVidia forums ? I have mixed results
with registered devs site. Maybe other paths are a faster ?
Cheers,
Wojtek Lewandowski

I've just tried this, and indeed: Setting Threaded Optimization from
Auto to Off yields the "good" result.
So maybe we should try to reproduce this with pure OpenGL and send a
sample to NVidia (they have been very responsive in the past if you send
an example)
cheers

Dear Wojtek et al.,
This mail reminded me of an issue I had a couple of years ago with VBO's
on a particular Windows pc with a 9800GX2. I thought it was an issue of
that PC, as it was quite unstable, so I didn't report the problem at that
time. The solution I accidently found back then was to turn off Threaded
Optimization in the NVidia Control Panel (Auto per default).
But now I'm getting the bad result of your test on a GTX 480 (266.58
driver), and that "fix" works again. After turning off Threaded
Optimization, I see the proper gradient displayed.
Could you try this as well?
Kind regards,
Ruben

tested on two more for you, both Debian 32-bit.
1:
dual nvidia GTS250s, driver 270.41.19, good result across 4 screens.
2:
nvidia 9600GT, driver 280.13, good result on single screen.
