White looks gray in Overprint Preview
The recent update to 29.8.1 now shows whites as grays in overprint preview. This changed feature now added leaving users unable to turn it off creates a massive problem when building anything containing white elements that are mixed or overprinting with or near grey elements. It is also a huge issue when sharing PDFs created in the new 29.8.1 with users who may not have the wherewithal to open their settings and start changing overprint settings.
Having been an artworker using Illustrator for over 20 years now, in which time I have seen some real clangers get through, but this for anyone in working print and design or any end user viewing a shared file, is a complete and utter disaster which when combined with the recent adobe Acrobat issues with the new ui being implemented against thousands of complaints and comments on the adobe forums really is the final straw.
The bigest issue is that it white in overprint preview is no longer white and becomes a gray which when working with other greys some of which are overprinting with overprinting whites set into the artworks due to print process requirements, shows tints close to 10% or light gray pantones as the same visually as a white as can bee seen in the attached.
I will now potentially be advising my employer to investigate alternatives to adobe cc as it is now across the board becoming too unstable a software to reply upon. We have already moved away from acrobat company wide due to increasing costs, but these sort of issues fast become a game changer for who's software we are able to use.
I have to assume that you are not researching any of these changes with your users as they are seemingly only consistent in their lack of research to them.

Egor - This does not look related to artboard color.
Iain - Thanks for sharing the file. We will investigate this. Would you let us know the version you were using before upgrading to 29.8.1?

Additional info.
I do not see this a file specific issue as a PDF file created from an ai file version I created the day before the update views ok in Acrobat, yet the one from after the update shows whites as greys, only difference between the files being when they were created pre and post update. -

Here is the ai I created to show how the overprint preview when using spot whites turns them to grey.

Iain, some changes were made recently to allow artboards to have background color, and this might be related.
But it’s hard to tell without the test file — can you please share this exact document here? The team would need it to study the issue.
I can’t replicate it on my side, so perhaps it also can be OS or file specific.
Please share all the details about your OS, GPU specs.
