[snip - summary: after recursive cp, some file has the wrong size]

I don't have any good ideas about the cause of this problem, but since I
didn't see anyone else replying, I'll suggest some investigation techniques.

Run cp --version so we know how far back in history we should look for
similar bugs.

cmp the two versions of the file to see if the short one is just truncated,
or if there are other differences.

Run df -T on the source and destination.

If it's reproducible, run strace -o cptrace cp ... and publish the cptrace
for others to look at. (If the files being copied are private, the names and
contents will be in the trace so you will have to inspect it yourself.)
