In Lightroom Classic, images look normal in Library, but in Develop mode black areas are covered with blue pixels and white areas with red pixels. This started appearing unexpectedly on a Mac Studio, and changing the graphics processor settings did not help. What causes this, and how can I turn it off?

Well after figuring out that the whites also displayed as red pixels, I was able to search more effectively for an answer and found this:

It's more than likely just the clipping indicators are switched on. Press "J" to turn them off if you don't want to see where the image is clipped.

This is most likely Lightroom’s clipping warning overlay, not a display or GPU problem.

In the Develop module, Lightroom can highlight:

blue for clipped shadows/blacks
red for clipped highlights/whites

That’s why the image looks normal in Library but shows colored overlays in Develop.

To turn it off:

press J to toggle clipping warnings on/off, or
click the small triangles at the top left and top right of the histogram in Develop.

If you want to use the feature, leave it on to see where tones are clipping. If you don’t want the colored overlays, disable both indicators.
