I have upgraded and yes I have had, and still have problems with ACR, Photoshop, LR and ViewNXi after spending considerable time attempting to resolve. The problem I have is in the area of colour management. I did not have the same problem with running Win10.

PROBLEM -

When I open an image in ACR (raw or jpg) the colour is correct to my eye, whites are white and greys are grey. My monitor is calibrated. I can use the few different monitor profiles, latest and previous, that I have and whilst there are very minor differences whites are still white.

When I open that same image in PS whites are no longer white and the image has a yellowish hue.

At this point let me emphasize that my concerns/problem is not one of colour 'accuracy' but of colour 'difference' between what I see in the two different applications, ACR/PS.

When I save the image I am viewing in PS that has the yellow hue the resulting image is then as I viewed it in ACR, correct as far as I'm concerned.

In ViewNX that same image has a yellow hue. In LR develop mode the image is correct but the thumbnail to the left has the yellow hue.

INVESTIGATION -

There are references to this same problem on a couple of other forums I've found, along with references that Win 11 has not yet been fully tested in the colour management area. I have checked and rechecked absolutely every colour management setting but I can not solve it.

At present my workflow is that I only trust and use the 'colour' I view in ACR but I know that whatever I see in PS although the colour is wrong, will save correctly.

It's unclear if this is a Win 11 colour management or possibly a Graphics card compatability glitch.

P.S. Every other aspect of the update to Win 11 went faultlessly.

I tried the search function but came up empty (as usual). I'm wondering how many of you that subscribe to Adobe (Lightroom, Photoshop, ACR) have completed this Windows upgrade and if you have had any problems running the Adobe programs afterwards. I'm a bit leery about this upgrade as my Dell desktop computer must be at least four years old and everything is currently working just fine. But I'm getting messages that indicate my computer is able to accept this upgrade. I look forward to your insight.
