bug with colors when minimizing the game

after the last update every time I minimize the game or switch to another application and whenever I return to the game the colors are very saturated which forces to close the game and play again. before I could exit or minimize the game and did not have this problem, the video drivers were updated but fault persists, and it seems that the fault is not the game as such because when recording screen or take screenshot with f12 looks good to review, it seems to be steam problem or I do not know.
