GreenHopper Rapid Board does not display issues correctly

Using the rapid board, I can see some of my issues, but many of them are "hidden" for lack of a better word. See screenshot - it's like there's a big white "box" in the middle of the screen. Using JIRA 4.4.3 and GH 5.8.3, tested in Chrome and FF (newest of each) and on multiple machines.
