I also have seen this and while its quite minor now, I suspect it may get worse
over time. I believe its dust particles not condensation. The only solution that
I've yet to try is to get a can of pressurized air and blast the corners or openings
to see if you can clear the screen. *do this in the dark with sidelights ON to see the
air rush in and clear the screen* Of course, there is a more drastic way of
fixing the problem and that requires screen surgery to gain access to the underside
and wipe clean. (would also be a good time to seal the openings (if any) since
that is the nature of the problem.
