The first frame of logs are not being parsed and rendered. A simple way to recreate this bug is to take a log in roboviz of an empty field (you can move the ball around on the field if you want). When loading the log the first frame is not parsed and rendered which, as it is the only full state frame, results in the log just being shown as a black empty screen. If you rewind the log the first frame will then be parsed and things will work normally. This bug is a regression in the behavior of the original version of roboviz.
