Multi-channel file displaying black

[Philip Muller]

I'm using Photoshop 24.5 on an Intel iMac running macOS Ventura. 

I work in multi-channel everyday for my work in commercial print design. Since updating to the latest version of Photoshop, I'm experiencing an issue causing black to display instead of the colors in the art. Sometimes the issue is not there; sometimes the images are all black; sometimes a part of the image is solid black. This can changed depending on my zoom level. Sometimes it goes away when I restart. Sometimes it doesn't. I've also been seeing the issue across different files, but I think I've only seen it while working in channels. Below is a screen recording of the issue.

HI @Philip Muller see this page regarding the removal/support for Pantone spot colors in Adobe Products:

Thanks. I'm actually not working with color books. I updated to 24.6 and I'm not seeing the issue for the time being.

Look at your preferences for display native canvas and or other GPU related settings.

Hi @Philip Muller if the black is not tied to a specific spot channel, etc you can also try going to Photoshop Preferences/Technology Preview and check “Disable Native Canvas”.  Relaunch PS after.

I had that same issue this morning. Tried the 'clean' method, which is really a delete the app and download again. Tried the 'fix creative cloud' method. Still showed a HEIC image as just black.
Changed color mode to CMYK (did the same with LAB)... image displayed correctly. Had to save out as CMYK. Opened the attached CMYK jpg back into Photoshop... convert to RGB... black screen for image!!!
So, for me... have to assume a bug.
