Hi Sherman, This sounds like a precision issue related to the computation of the text scaling - which is done in floats.
Could you modify the osgfadetext example to have text they way you are setting it up and see if it reproduce the problem, or perhaps send a small .osg file that reproduces the issue and then I can have a look at it. It might be that we need to have a code path in osgText for using double maths internally. Robert.
