Recently I noticed a minor appearance problem on this forum:

The %username%, Inbox, and Alerts buttons all show in white and black after I click on them.
I only started seeing this behavior about one or two weeks ago. Before that, the buttons were a nice blue gradient after clicking on them, as expected. It seemed like the problem started happening right around the time I updated Flash Player to version 16.0.0.287. However, I don't think it's related to Flash, since I've observed it on Fedora Linux (for which Adobe now only releases security updates to Flash) as well as Windows XP and Windows 8.1.
