Hello Folks,

I am using OSG to render a scene and take a huge number of screen shots
from of tons of different orientations and positions.  When looking at the
rendering through my viewer, everything looks correct.  However, when I
look at the saved screen shots, there are obvious artifacts.  It looks like
rolling shutter camera has been caught in mid capture.

You can see what I mean here :
https://www.dropbox.com/s/xj2dakjkuyw8d0v/view381.png  The discontinuity is
on the right hand side.  The top looks like a new rendering while the
bottom looks like the old.

I am using an osg::Image to read the screen buffer during a the main
camera's post draw callback.  Has anyone else experienced this kind of
problem?  Most of my captures are OK, but greater than 1% captures are
not.


Thank you for any help you can provide.
Cheers,
Adam
