I am running Windows 8.1 64 bit v 8.1 6.3.9600.17415. I have an nVidia Quadro K600 graphics card. I have recently upgraded to Bridge 220.127.116.112x64 and Photoshop 19.1.3. At the time of upgrading my Adobe products I was using the latest driver update which had been installed a day or so earlier. My issue since upgrading Adobe is when I view a raw file in Bridge the colours look fine but when I open it in Camera Raw the colours are horribly distorted. However, when I then open the image in Photoshop the colours are fine again. I have turned graphic processor acceleration OFF in ACR preferences but this hasn't helped. The odd thing is that if I toggle away from ACR then back to it, the colours shift back to normal (ie the same as appears in Bridge and Photoshop). I have rolled back the graphics driver to an earlier version but the problem persists.
