When I attempt to edit photos in the most recent update of Lightroom I find now that switching photos creates these strange color blocking artifacts on my photos. It makes it kind of annoying to really edit the photo in great detail. It's like taking a computer and turning the screen color bits down see here. Can anyone explain why this happens and help me stop it? I have attached a screenshot of what I see.
Then after zooming in on the file it renders the correct color (please pay attention to the waves), however I have to do it every time.
Check here to see if it looks like it could be your issue: Optimize Lightroom performance (deleting preview cache). To help anyone else trying to answer, where exactly do you see the images with artifacts - in Library, or in Develop view?
