Update for Photoshop CC 2018 broke Photoshop

I updated Photoshop today, as I have creative cloud. Whatever you engineers did, you broke the program. As I am working, if I switch screens, and go back, the image becomes invisible and the screen is all white. I try saving the image, and it never saves, but locks up the program. I have to end task, then restart the program. How annoying! It was working fine until this update. Really, really frustrating. Makes me not to want to update anymore!! Now I am screwed with a program that is broken.
