Lightroom CC freezes shortly after I start working in Develop. It first slows down, then stops, then a white cast appears on the monitor and the page name shows "not responding." I have to force the program to close.
This started happening several weeks ago but I was traveling and couldn't address it then. In the meantime, I have installed Windows 10 replacing Windows 7, and updated CC in a major update. The behavior of Lightroom is as before, however, and it still freezes.
I've used LR for many years but I am not that comfortable tinkering with the program so I have not pursued any troubleshooting. Help would be appreciated.
The first thing to try: Disable the option Preferences > Performance > Use Graphics Processor. This has solved the problem for most people reporting your symptoms.
Looks like the answer. Many thanks.
