Here's an alternative view....
What picture viewer or s/w are you using to view the picture?
I feels very much like the viewing program had a "gamut" indicator enabled? A gamut is the range of colors that a color system can display or print. The spectrum of colors seen by the human eye is wider than the gamut available in any color model. When it fall "outside" the range, certain graphic editing program or viewers has the ability to indicate that to you. It can be indicated as some bright or flourecent green which can be static or blinking over those areas. It can also be an over or under exposure indicators. If you have scenes with white out sky, bright parts or dark shadows where the sensor can not detect details it will indicate that out to you in the same way as the gamut indicator.
Check out if you have that kind of built-in indicator in your program...it just might be what's causing the blinking in specific areas of pictures whenever you view your photos with the program. If you scroll the pictures and thos blinking patches follow it in the same spots, that is most likely it.
