First, try disabling GPU in the preferences (Performance). Any better?

If turning OFF the GPU works, it's a GPU bug, and you need to contact the manufacturer or find out if there's an updated driver for it. This is why disabling GPU is an option as more and more functionality moves to the GPU in newer versions of many Adobe products. Disable third-party graphics accelerators. Third-party GPU overclocking utilities and haxies aren't supported.

If the GPU and display profile isn't causing the problem, see:

Thanks very much Andrew! GPU was on so I turned it off and, so far, all seems fine!
I'll follow the other advice if it comes back...


Update: All still fine. Hopefully that is all it was! Thanks again!

Glad to finally have a workflow to show XDR/HDR images at full brightness on iOS/mac devices (which are capable) from my raw files
