@NateT My ISP has given me a confusing maze of networking problems over the years which were due to intermittent or totally disconnected network connectivity, but through all this time I have never experienced any graphical errors in the question or answer boxes of any Stack Exchange network site.

@NateT I just found a new and somewhat confusing feature on a Stack Overflow page. A long answer grays out the last three lines until the last line is almost unreadable. If you look closely you can see a blue "Read more" link under the grayed out text. When you click the link it shows all of the text, and the link changes from "Read more" to "Read less".
