I just came across a strange issue of a dot in the background of an image which changes colour when I zoom in.

Here it is when not zoomed in:

 

Here it is when zoomed in:

Here's a screen recording of the dot changing colour when zooming in and out: C1 dot changing colour.mov

The colour when zoomed in looks correct, but when I export the image, the dot looks like it does in the first image, i.e. when not zoomed in.

Any suggestions why this is happening?

  This is what it looks like when viewing the original raw file in macOS's Finder:

  Finder is not rendering raw data. Finder is extracting the embedded JPEG preview.

  You're right. The raw file looks the same in Photoshop though:

  I found out what was causing this problem: Dust removal.

  I had used the automatic dust removal function, and resetting it solved the problem.

  In any case, this doesn't seem like correct behaviour.
