Please turn off the Graphics processor from the Lightroom preferences and check if that helps.
Open Lightroom > Edit Menu > Preferences > Performance tab > Uncheck GPU > Restart.
Hello, I tried this mid December - I haven't been able to use the program since early December, this post is tagged today because I updated it with more tags since I got no resposnes.
I had to turn off the flu manually through the code because it would freeze before I could turn it off. For some reason I have Lightroom cc 2015.7 & Lightroom cc 2015.8 on my computer although neither works. The program is low to launch and if I click too many times (more than once) the entire thing freezes and says not responding. I also get other small windows from Lightroom that open in the background like Bezel.
