Does this happen while also capturing video or is audio capture enough to trigger this bug?
If video and audio has to be captured to trigger this, is it related to screen capture or any video source?

Does not happen with audio only, you need video. It also does seem related to screen capture, as I couldn't reproduce it with CamTwist? or FaceTime? selected as the video device.
