It seems to be an issue with the Graphic Card drivers, I would suggest you to please update the Graphic Card Drivers.
Also please check the Monitor Profile : How do I change my monitor profile to check whether it’s corrupted?
Hello, Thanks for your answer. I have an apple computer, an Airbook 11 inch, I cannot find any reference to updating the Graphics Card Drivers, I assume I cannot do that. Do you have any other ideas for me? Thanks-M
Could you please check Lightroom in a New User Admin Account, also could you please let me know which Graphic Card do you have on computer .
This is caused when a hardware malfunction somewhere has corrupted your image.
This hardware malfunction could be the camera card itself, the transfer hardware, your hard disk or your computer's memory.
You need to transfer the photos from the camera card to the computer again, this time using different hardware (and if possible transfer to an entirely different computer) to see if the problem goes away, and then isolate the specific piece of hardware that is causing this issue.
