Please try and turn off the Graphics Processor from the Lightroom preferences.
Go to Lightroom Preferences from the Edit menu
Click on Performance tab
Uncheck the Graphics Processor
Thank you for the suggestion. Unfortunately that did not seem to resolve the issue.
If you have Lightroom CC, the simplest solution is to install the Lightroom app on your iphone and import images there. The images will show up automatically on your desktop (make sure you logon to LR/mobile on the desktop too)
The latest Lightroom CC update fixed the issue. Thank you!
