The display for aperture (i.e. f/2.8) disappears and then re-appears on the LV screen. In the menu system, the Aperture menu item under Expo turns itself off then on, presumably a symptom of the same problem.
If exposure override is turned on, there doesn't appear to be any change to the image. If exposure override is OFF, the image changes brightness then back, again presumably a symptom of this issue.
