Lightroom CC 2015.9: System hang when using Develop module

After I installed the latest version CC 2015.9 I got serious crashes. When I'm working in develop mode the screen gets a lot of small dots all over and everything hang up. I have to force the computer to shut down. When I restart there is yellow vertical lines over the screen with about 5" between, and the computer do not start. I have to start in error safe mode two times to get the computer back to work. Same thing have happened two times. This did not happened in the version prior to this. There was a problem with the tools panes on both sides of the image went away and left black areas, and I have to close and reopen the app to get them back, but that was not a problem as serious as this.
