I'm using Lightroom (Current Version 6.5.1) for a while now, but a few days ago colors in my pictures started getting weird in some areas of the picture. That effect doesn' affect all the Pictures. Some are OK. I tried turning off using the graphics processor and restarting, but that didn't help. Also last software update didn't have an effect.
Here's an example:
Anyone who has an idea how to resolve that Problem?
Your photo has been corrupted because of a hardware malfunction. It could be the camera card, card reader/USB Cable/USB port, hard disk or memory.
You need to perform some diagnostic testing to determine the bad component. Try importing the photos again using different hardware. If possible, import to an entirely different computer.
Thank you, that hint really helped me. Seems like my WiFi USB dongle causes the errors. When I connect to my NAS by cable, these bit errors don't appear in the JPGs.
