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.
