Hi,
I get texture corruption if copypixrate or subtexrate is run without
being the top most window.
This is not a new problem, I just just happened to discover recently.
When a window is partially covered by another window, or off the edge
of the screen, reading pixels from those areas gives undefined results
(because there's no backing store). That's within the OpenGL spec.
