I like the new design, the new full-inverted icons for read and unread are much simpler to distinguish between than the darkish-gray and grayish-blue icons were in the past.
However for the specific case of "hot topic, and you have posted into it, no unread messages" I see the old-style icon (red icon with green arrow in the bottom-right corner).
See attachment for this feedback board (http://www.developer.nokia.com/Commu...Nokia-Services) it applies to the RDA-firmware sticky and to the Launchpad woes thread.

Checked with my non-regular browser too, so it is not a caching problem.
