Hi,
Have you tried forcing single threaded?
maybe see this thread.
"Complete garbage in OSG / XP / multi monitor / multi threaded / NVidia"
Don't know your setup, so I'm guessing.

Hi all,
I am currently using a osgViewer::viewer with slaves cameras (just like
the osgwindows example), and I am getting some visual artifacts on the
second window (see the attached image).
Does it rings a bell to anyone ? Something not setted correctly ?
Thanks in advance !
PS : here is my viewer init :
osgViewer::Viewer viewer;
// upper window + upper slave camera
{
osg::ref_ptr<osg::GraphicsContext::Traits> traits = new
osg::GraphicsContext::Traits;
traits->x = 300;
traits->y = 40;
traits->width = 600;
traits->height = 200;
traits->windowDecoration = true;
traits->doubleBuffer = true;
traits->sharedContext = 0;
osg::ref_ptr<osg::GraphicsContext> gc =
osg::GraphicsContext::createGraphicsContext(traits.get());
osg::ref_ptr<osg::Camera> camera = new osg::Camera;
camera->setGraphicsContext(gc.get());
camera->setViewport(new osg::Viewport(0,0, traits->width,
traits->height));
GLenum buffer = traits->doubleBuffer ? GL_BACK : GL_FRONT;
camera->setDrawBuffer(buffer);
camera->setReadBuffer(buffer);
// add this slave camera to the viewer
viewer.addSlave(camera.get());
}
// lower window + lower slave camera
{
osg::ref_ptr<osg::GraphicsContext::Traits> traits = new
osg::GraphicsContext::Traits;
traits->x = 300;
traits->y = 275;
traits->width = 600;
traits->height = 480;
traits->windowDecoration = true;
traits->doubleBuffer = true;
traits->sharedContext = 0;
osg::ref_ptr<osg::GraphicsContext> gc =
osg::GraphicsContext::createGraphicsContext(traits.get());
osg::ref_ptr<osg::Camera> camera = new osg::Camera;
camera->setGraphicsContext(gc.get());
camera->setViewport(new osg::Viewport(0,0, traits->width,
traits->height));
GLenum buffer = traits->doubleBuffer ? GL_BACK : GL_FRONT;
camera->setDrawBuffer(buffer);
camera->setReadBuffer(buffer);
// add this slave camera to the viewer, with a shift right of
the projection matrix
viewer.addSlave(camera.get());
}
