I have used Lightroom and Photoshop for years and upgraded to CC about 6 months ago. I just got a new computer and downloaded both Lightroom and Photoshop CC onto the new machine. In Lightroom, when I send an image to the Develop module, all I get is a blue screen where the image should be. The navigation panels, and develop panels show just fine, but the image does not appear on the main screen. It does appear in the Navigator. What's up with this?
Turn off the Use Graphics Processor in the Performance tab of the LR Preferences. Blue box will be gone, Image will show.
Where are the preference/performance tabs located? I too have this Blue Screen issue
