Hi J-S,
Fyi: I tried to go back in time w.r.t. nvidia drivers but the helpful
(sigh...) windows update kept installing version 196.21 somehow...
I installed 196.34 (from laptopvideo2go) and the problem is still the same.
I do have the OpenGL knowledge but lack of time to dive into this.
Is it so that 2 windows are created by the osg, instead of 1 window that
spans accros these 2 screens? It seems to me that that is the case,
judging from what happens when you focus the window on the 2nd screen:
the first window does not go to the top.
Is there a way to let the osg open just 1 window that spans accross the
2 monitors?

Hi Raymond,
I hadn't noticed this because I always start up osgviewer fullscreen on
my second monitor only, or in a window.
And about this, I think this new problem might be related to the weird
behavior I and others have noticed with OSG apps before:
- Start fullscreen on screen 0 : the app will show up, then the screen
will turn black for a few seconds and then it will come back (annoying
but it's ok after a few seconds).
- Start fullscreen on screen 1 : the app shows up and stays that way
(that's how we'd like it to behave every time!)
- Start fullscreen on both screens : the app shows up on both screens,
then the screen turns black for a few seconds, and the image comes
back on the first screen but the second one stays black (that's the
new problem, before the image came back on both screens after turning
black).
So I think I'll submit a bug to nVidia in any case. It would be nice
to have them look at it and see if there's a problem in their drivers
that's causing this. I haven't seen this behavior on other apps (games
for example) but those are generally hard-coded to work on only one
screen (the first)...
If anyone with OpenGL knowledge would like to code up a quick straight
OpenGL app that can start a graphics context in fullscreen and we can
specify which screen or both, it would be interesting to see if this
is reproducible then.
