While editing some photos today from yesterdays shoot I found- after editing- a few of the photos had strange patterns over parts of them. It happened in the jpg exports as well. At first I was thought it was a sensor issue but the photos look fine on the camera screen. I shut down LR and restarted the comp. Went back to Lr to check the photos. By clicking between library and develop modules I was able to get the photos to export a jpg without the issues. One of the photos still shows the patterns in the library module and navigator preview window but it is fine in the develop module.
Lightroom CC. I havent updated to the new version yet (classic) as I have been in the middle of too many projects the past few months. Windows 7. 16 gigs ram.
Anyone ever have this happen? Theories, suggestions... ? Pics attached.
