Don't have an answer, just some debugging ideas.

 - Does perfly print any unusual warning messages?

 - Does the same thing happen if you run perfly locally on the Linux
box? (no remote display)

 - Does it only happen with perfly or other Performer samples also?
(e.g. simple.c)

 - Do non-performer (e.g. pure OpenGL) apps have the same problem?

 - Can you run the Windows version of perfly natively on the Win box?

I don't know what to do if any of the above answers are "yes" :-) but
the questions define enough half-spaces to at least be able to narrow
down the root cause..
