I am experiencing sporadic color shifts to Leica M 262 .DNG images in the Develop Module of LR 8.0. I am running macOS Mojave on a 2012 Mac Mini with graphics processor acceleration disabled. The camera has the latest firmware. This doesn't occur with all images, but seemingly at random, and without any user input. In the Library Module, the images appear normally. (I had reported this issue with earlier versions of LR and an earlier OS, but the problem was never resolved, and unfortunately persists even in the latest release.) Please see screenshots below. First, here is the shifted color seen in the Develop module.


And here is the image as seen in the Library module.


FWIW, I am using the Embedded color profile. Also, this problem does not occur with DNG images from my Pentax 645D camera, only with the Leica.

As a long-time Lightroom user, I find this to be a source of great dismay.

If you have a file that displays this consistently, would it be possible for you to share the file so we can attempt to duplicate the color shift on our end?

Here is a Dropbox link to the file pictured in my Problem Report of yesterday. The color shift occurs on a hit-or-miss basis:

Thank you.

It looks good on this end, Robert. 

When this happens, if you export the file does the exported file show the color shift?

As I say, hit or miss. Sometimes clicking on it seems to trigger the shift, sometimes not.

Don't know about result when file is exported. I'll give it a go sometime later today.

Thank you.

One thing that is odd as shown in your Develop loupe screenshot, the matched camera profile is shown as "Embedded". Normally, it should shown as "Adobe Color" as the new default. Are you setting up to have some custom camera default http://blogs.adobe.com/jkost/2017/09/setting-custom-develop-defaults-in-lightroom-cc.html or applied some develop preset during import?

Yes, I have set the Embedded profile to be applied on import.
