Color Management enabled, displays desaturated images

[tsdevine]

I have a M1 MacBook Pro and have an issue where PM+(Photo Mechanic Plus Version 2024.10, build 8173) shows images somewhat desaturated from what I see in Photoshop.   I have perform color matching enabled, and the images are tagged as sRGB IEC61966-2.1.   This happens when I'm using the Apple Silicon "native" PM+.   When I switch back to my latest "pre" subscription Intel version of PM+ (Photo Mechanic Plus Version 6.0, build 7212 (90865b3), images look the same in PM+ as they do in Photoshop. 

Any idea what might be the issue?

Thanks,
Tim

It's a bug we recently discovered in the Universal build. In my testing of this issue it actually seems to depend on the size of the window, so as I drag the window it will alternate between the desaturated color and the correct color. The customer that originally reported the issue reported the same. Of course, we will be publishing an update to fix this so that it always displays the correct color, but for the moment, if you resize the preview window a bit, do end up seeing the correct colors?

Yes, if the window is > 90-95% coverage of the screen, it desaturates.   If the window size is less than that, then it goes back to the correct color rendition.

I guess in the meantime, I'll work with a slightly smaller window.

Thanks for the quick reply.

Any idea when this will get a fix?   It's getting super annoying.

I'd like to fix it today.  I have been unable to reproduce it on my system.  If you can help me reproduce it, I'll make it my #1 priority to fix it.  I have tried resizing my Preview window to all ranges of sizes from very small to very large and I'm getting consistent color rendition.

Well, I'm not sure I'm "doing" anything to make it happen.   It seems as though it may not happen with all images.

I have one that "seems" to be often affected, as an example.   I'm not sure it's the image though that actually triggers it.

What ICC profile does it have, if any?  What do you have your default profile set to in the Color Management preferences?

Image is tagged this way

ICC Profile: sRGB IEC61966-2.1 (embedded)

I have no default profile selected (the setting seems to imply that it will only use the default if it can't be determined from the image.)
