I am progressing with the fixes for this - there are/were multiple
overlapping bugs that cause the problem, mostly in the refresh code
which is a nasty ball of hair.  I think I have all the positioning
errors sorted but there is still a clearing efficiency issue.

For the coredump issue please raise another PR, it isn't good to
conflate a couple of issues into a single PR.
