I can confirm I see the same behaviour with the latest CPAN versions: 

c:\test>junk6
threads version: 1.71
threads::shared version: 1.26
By taking a reference first...
w r a x d j y u k h ...and so on

By de-ref the shared hash-of-hashes each time...
w w w w w w w w w w ...and so on

And I can't see any obvious cause either. If you haven't already done so, you should raise a bug report.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
"Too many [] have been sedated by an oppressive environment of political correctness and risk aversion."
