Demul AMD and color problem

Hi all,

i have a big problem with my ryzen 2200g and Demul.

I see this problem in atomiswave game like hokuto no ken and all other.

So, if i launch the game in windows mode, colors are right, if i launch the game in full screen my colors gamma is wrong. If i do F4 and enter in test mode and go in to the color screen, white and green are right, but blue are red and red are blu =(

If i do alt+enter for 2 or 3 time i have a full screen with right colors, but windows color are inverted.

I have problem only with demul and no with other emulator or game =(

I have just update at laser 28/4 versione. Plug in dx11 amd lates vga driver for ryzen 2200g =(

Hope that someone can help me
