To repro: make sure you select the Video (not Photo) option. Then click the (now-red-inner-circled) Record button.
The white selection/area pane will remain, with the rest of the screen dimmed, until you stop the recording. How do you stop it? Look for a small control, with a white-on-red black square to the right of a counting-up timer for the video, and click that little square. So it's not so much a "bug" as a surprising, if not almost-hidden (especially for those of us with kinda-largish monitors), behavior.
