What are these "things" in my RAW images?

Every so often I come across an image that has these semi-transparent colored squares and I can't figure out where they are coming from. On a few other images it seemed like the cause was something to do with CA/defringement adjustments, but in this image neither of those sliders make any difference.

Surely I can't be the only one to have noticed these things, but I can't seem to come up with any applicable search terms to find an answer.

Since what you are seeing isnt your raw file( you cant actually see a raw file) have you tried converting it via different methods methods? DPP vs LR or ACR to see if its actually embedded in the image or just an artifact of your processor or processing somehow?

So I should have said my .DNG file. They are present when converting CR2 --> DNG using LR, and CR2 --> JPEG using DPP. I am doubting that it has anything to do with the conversion process because there have been times when defringement controls induced the same artifacts.

Weirdest looking flying saucers I've ever seen

Seriously though, do you get the same issues when shooting in JPG?

I haven't shot in JPG in years, so I really don't know. I can't even compare the same shot in JPG and CR2 because it only occurs on probably less than 1% of photos. FWIW, I've never noticed the artifacts when looking at the image on the LCD...however, I never actually looked for the artifacts either.

Does it do this with different cards or always the same card?

The raw files have a small, embedded jpeg that is used for viewing, both on the camera LCD and on the computer when reviewing images in a folder. Have you ever noticed these artifacts when looking over your unconverted images?

Can you post an 'infected' Raw file somewhere?

What you are seeing is indicative of having the Purple and/or Green Hue sliders quite far apart and the Amount turned up near maximum in the ACR/LR Defringe tool. If you really need the Hue set that wide and the Amount that high to remove some fringing then there are two options involving the local adjustment brush. I first you set the Hue sliders, then turn the Amount to zero and use the local adjustment brush set to a high setting to paint in just the spots that need defringing. The other option if you have lots of fringing that needs fixing, and not too many of those blocks, is to use the brush with the fringing tool set to -100 and to paint the correction out over the affected area. Which method is best will depend on ratio of areas with fringing to that of the mis-coloured blocks.

It is the Defringe tool, not the CA correction that causes this to happen, and usually only when you have a very high amount set.

Manneti, are you using the Defringing eyedropper to find Adobe's recommended settings?

Post a screenshot of the sliders of the defringe tool.
The screenshot is a "before", but if it's a DNG that doesn't mean all sliders are at default (or what your default is)…
Second (wild) guess is a videocard issue, but then the jpgs wouldn't have it (I think).
