Take a look

Alright so i have this same thing, it happend cuz i selected the bloom option on during instal.

The only way to turn that off is by editing the configuration files.

How to do this, i have tryt my self and it still is blinking like hell so i must have overlooked something though to find bloom related config files you do the following.
First in the windows folder options turn on the option to see hidden files and folders, next go to appdata map. There you look in the local folder.
You will see an map called Discovery 4.88.1 go in there, go to the folder called Exe. In there is a file called enbseries, open that one and after some light scrolling you will see bloom related entries.
Adjust those entries untill that blinking stops when booting up the game.

Hope this will help you out, much luck and friendly regards from.
