This has happened to me on a number of occasions. When I have an edited image open in the Development module and I hit \ the hint in the top right shows as "Before" but neither the images nor the navigator thumbnail are updated.

Are you on Mac or Windows? It might be a graphics driver issue. Try unchecking Use Graphics Processor under Preferences > Performance. If that fixes it, try updating your graphics driver directly from the manufacturer:
