I have seen a similar problem to this, but only with paged terrain
databases. My problem was that the second view would not load textures
that had already been loaded by the first view.
Calling
view->getDatabasePager()->setUnrefImagedataAfterApplyPolicy(true,
false);
fixed it for me, but I've never been sure if that was the "correct" way
of fixing the problem. I'm not sharing contexts between the views
(perhaps I should be).
I'm currently running 2.9.3 but have seen this of 2.8.1 as well - on
nVidia with the latest drivers.

Hello Roger,
I remember running into a similar problem that I attributed to
an nVidia driver bug. You might want to try upgrading your driver. I
worked around the problem by calling dirtyTextureObject() on each
texture in the model whenever I created a new window, forcing the driver
to reload the texture data from system memory. I think the driver got
confused with shared contexts and this function was an effective
reminder of what the texture data was supposed to be.
Regards,
Mark

Subject: [osg-users] osgViewer::CompositeViewer Texture Issue
I am upgrading to OSG 2.8.1 from OSG 2.4 and am having a problem
with use of the osgViewer::CompositeViewer. My application
adds/destroys views dynamically and I am having an issue when I have two
views loaded with the same terrain/textures (for example a terrain) when
I close one view the textures in the 2nd view all get removed from the
scene. The only way I am able to get the textures in the remaining view
to reload is to close the view, leaving none open, and opening a new
view. This process destroys and recreates the composite viewer.
I have tried calling setUnrefImagedataAfterApplyPolicy(true,
false) on each view as they are created but this has not helped resolve
the issue.
Can anyone provide any advice to help with this?
Thanks,
Roger
