Could you please unchecking "Use Graphics Processor' From Photoshop's Preferences > Performance, then relaunch Photoshop and check if the issue still exists.
Thanks! I'll see if this does the trick and I'll try to remember to check back. Last time this happened was probably a month ago. By the way here is my graphics card specs.
AMD FirePro D500 3072 MB graphics
I checked for updates. Photoshop is up to date.
As you've mentioned that you're using Photoshop release CC 2017.0.0 the latest version is CC 2017.1.1. You can check the version of Photoshop by going to Help > About Photoshop CC. Please make sure that you are using the latest version.
If you are not able to see the update in the creative cloud application then, please sign out then sign into the creative cloud application.
