World color changes after a while

For some reason the colors of my scene start to adjust when i play.
as you can see in the video linked below you can see the colors gettin brighter and normally when i look down again the colors go a liitle bit back to normal, does everyone have this problem or am i the only one,

EDIT: It seems to be a kind of post processing problem, when i lower the post processing quality the color changing goes away, but i want to keep it on ultra

thats auto exposure.
google it and you’ll find a loooot of answers :slight_smile:
