AFAIK this is a known issue.  I suppose that you need AR-6 for
transparency which doesn't exist (yet) for Linux.  But I don't know,
Hans Hagen is the guy who can give you a definite answer.

pdftex includes libpng, don't expect improvements in pdftex if libpng
is not updated.

strace is a program which records system calls.  It seems that
acroread has nothing else to do than permanently ask the operating
system "how late is it?".  See below.  I've never seen something like
this anywhere else.
