If you are using DrawThreadPerContext or
CullThreadPerCameraDrawThreadPerContext then the draw thread will run
over the end of frame() or even run().
Call viewer.stopThreading(); to ensure the threads are stopped.

W.r.t osgText not clearing it's GL objects properly, in theory
releaseGLobjects() should work, and should purge the graphics context
just fine. Looking at the implementation of Tex
void Text::releaseGLObjects(osg::State* state) const
{
TextBase::releaseGLObjects(state);
getActiveFont()->releaseGLObjects(state);
}
And
void Font::releaseGLObjects(osg::State* state) const
{
if (_stateset.valid()) _stateset->releaseGLObjects(state);
for(GlyphTextureList::const_iterator itr=_glyphTextureList.begin();
itr!=_glyphTextureList.end();
++itr)
{
(*itr)->releaseGLObjects(state);
}
// const_cast<Font*>(this)->_glyphTextureList.clear();
// const_cast<Font*>(this)->_sizeGlyphMap.clear();
}
Which broadly looks to be the right thing.
Robert.
