Hello , The Video Color Vibrance is not take any affect after change any option.
I have tested at windows media player, MPC-HC, Pot Player, get the same result.
But Video Sharpness, AMD Steady Video works well.
When I change regkey "EnableOCLShaders" to 0 by regedit, Video Color Vibrance works well just like Video Sharpness and AMD Steady Video.
What is this problem? And this problem has been existed since Adrenalin 2019 Released.
My Graphic card is RX570 4GB, Adrenalin driver is 2020 20.12.1, OS is win 10 20H2.
