Photoshop CS6: image corruption with Brightness&Contrast

I noticed some weird corruption happening while adjusting the 'brightness/contrast' with the "legacy" tickbox selected - Areas of layers disappearing in random patterns (check out the image below)

It turned out it wasn't just doing something funky in the preview, it was doing it for real, hacking holes in every rasterised layer of every Photoshop document I had open at the time.

It was irreversible. Cancelling the operation did nothing, CTRL Z did nothing, going back through my history states made it worse and worse.

Unfortunately before quitting I saved my work thinking it was just an issue with the display of the files and not the files themselves. But when I reopened them it was the same and as I studied the layers I realised they were all destroyed. The bug had ripped chunks out of every rasterised layer in every document I had open.

(hundreds of layers, a whole day of work and a lot of money lost)

What color mode and bit depth is the document?

Someone else just found a 16 bit/channel specific bug that might explain this.

Also: did you install the 13.0.1 update?
What OS version are you using?

Hi Chris,

the documents are RGB 8bit

Ah, I haven't seen the 13.01 update, I'm running 13.0, Creative Cloud's last update check didn't show it

0S 10.6.8 (I know this probably needs updating as well)

If it helps it's also done a similar thing when adjusting hue/saturation
