I had just upgraded my Lightroom to Lightroom CC (PC version) and have a problem.
In Library mode i can see all my photos normally, as usual. But after switching to Develop - i see only blue screen, like this:
But in this mode every instrument is working correctly, so if i (for example) will set Exposure to +5, i willl see the changes in the Navigator tab.
Does anybody know, what is it and how can I fix it?
Go to the performance tab in Lightroom preferences and turn off GPU acceleration.
Magic!!! Thank You very much!
