Good to see youŠ

I am not aware of any issues of displaying PDF/A files by PDF viewers that
specifically claim to be "PDF/A conforming viewers".
Remember that a PDF/A file, when viewed in a standard PDF viewer, WILL NOT
render according to the PDF spec. Here's a blog entry about this, along
with a sample PDF that demonstrates the situation -

That was the case A WHILE (say 5+ years) ago when the standard was first
introduced, but since then there have been two independent test suites
(Isator and Bavaria) published, which have been used by (at least the
major) PDF/A validation tools to ensure consistent results. Such
validation tools exist both in commercial as well as open source varieties.
Hope that helps.
