Yes, I appreciate that. The code was as it was because I actually *do*
need to render to the background OpenGL scene. However, the simplified
version was very useful in sorting the 1-pixel border issue. It came
down to default style for the QGraphicsView having a border around it.
Simple fix:

self.setStyleSheet('QGraphicsView { border-style: none; }')

in __init__ for GraphicsView. (actually, this highlighted another
problem that I didn't clear the background of the OpenGL, so it was
filled with all sorts or detritus. This is fixed in the github .py
file).

Yes, it seems to be a driver issue. It works fine on another machine of
mine.

Many thanks,
