Since I upgraded my Macbook Pro to Sonoma 14.5 and I updated my Lightroom it isn't displaying .dng files correctly - they all have colour stripes going vertically over the photos. Even .dng files that I previously have edited and are still in the LR library. Can anybody help please?

i would try to uninstall and install again and see if it fix it .. unless you have some open projects that you’ll lose idk, anyway I suggest you put your question in a forums where many people are using LR like photographers .. DPReview for example.

Hi, thanks. Yes maybe I ought to have put my qu in a different forum. I did contact Adobe and they suggested switching off the Graphics Processor in LR preferences which has sorted the issue but I'm not sure it's the best answer. Thanks for your response.

It could be the Graphics Processor Settings issue or a cache issue. Just go to Lightroom > Preferences > Performance. And, toggle the "Use Graphics Processor" setting. If it’s on, turn it off, and if it’s off, turn it on to see if this resolves the issue.
