I tried the latest one available from 3/30, and the graphs all have blocks/small empty rectangles in place of numbers and text. Should something like this be reported in the system or leave it alone since it's a dev release?
I saw the same problem. Usually stuff like that they're aware of, but you're right, it's a development release, probably the one that will get the FreeBSD 8.3 upgrade. I wouldn't open tickets for it.
