Thanks to the QC team and Allan Schaffer this problem has now been
resolved. The problem was that I did not treat the CVOpenGLBuffer as
immutable and I needed to. This wasn't a problem for Tiger but became
an issue with Leopard apparently because of changes in the QC imaging
pipeline.
The resolution is to use a CVOpenGLBufferPool and then use
CVOpenGLBufferPoolCreateOpenGLBuffer each time I want to render a new
frame. After the frame has been passed to the QCRenderer I then
release the CVOpenGLBuffer. Problem solved.
Thanks again to the QC team and Allan.
Cheers,

Things were all fine for Tiger. :-)
When it comes to rendering here's what I start with:
