Lightroom CC Photo Rendering Problem
MacOS Mojave - 2015 MBPro.
Canon 5d Mk III
I have several thousand photos in LR CC. A last batch seem to be rendering improperly. Have deleted and re-uploaded. Same problem. Have verified that the problem is not with the original files. And, to make maters more confusing, notice that the ribbon renders the photo fine. Any ideas on the problem? LR is up to date. As is my camera raw file (these are shot in Canon Raw). None of my other photos have had this problem (all shot same camera, same format). Not all the photos shot in this batch have the same problem. Just a number of them. Also, sometimes clicking on the photo will change the render (sometimes for the better, sometimes for the worse, but never to eliminate all the artifacts.
