I have a new Dell Inspiron 15 7000 laptop with an i7-4510U, Intel 4400 Graphics, 1920x1080 screen, and Windows 8.1. I have noticed that the display will brighten and dim when switching between apps. For example, going from a dark desktop background to a white background such as File Explorer, it will take the display about 5 to 10 seconds to brighten to the appropriate level. Going back to the desktop it will dim and sometimes even show a quick flash. I have the display set at 60% brightness and have turned off the adaptive brightens. Also using the latest Intel drivers. Exhibits this behavior on battery or AC. Never seen this on a laptop before.
