Intel or AMD would be another useful tests if you can.  Just scoping out
the problem can help.

As a general point, the OSG itself will be passing identical data to OpenGL
on each frame for this bit of geometry+texture, the only difference will
the modelview matrix so if you are getting different results each position
then it'll be down to the behaviour of the driver/graphics card.

Other things you could try are to change the way you manage the depth
tests/write by simply disabling depth test rather than using osg::Depth.
i.e.

   stateset->setMode(GL_DEPTH_TEST, osg::StateAttribute::OFF);


Another would be to use LINEAR filtering on the texture so see if that has
a difference.  Not that you actually want LINEAR, but it'd be a useful
check,

Robert.
