OK I've removed the zero page addressing and used absolute indexed.
This made no difference. However I found the bug.
A compare was wrong and I was doing the copy during the upper raster and not the lower. Hence the appalling tearing.
Epic Fail :-/
Thanks for everyone's input. I can now crack on with the main game engine now that my scroll routine is as smooth as silk.
