Try selecting Basic GPU mode through the Edit - Preferences - Performance panel as an immediate workaround.
Watch for updated drivers from your video card maker on their web site.
I currently have in on Basic... doesn't work, unfortunately.
Do you see the problem if you disable the [ ] Use Graphics Processor setting entirely (remembering to restart Photoshop before testing)?
What video card (aka graphics adapter) do you have in your system?
What driver version are you running?
Have you looked for alternative versions e.g., on nVidia.com or AMD.com?
Wow... it WAS working, just fine, until about an hour ago. I have Use GFX Processor unchecked. I've restarted my computer, downloaded a driver update from Intel, and nothing. I have an Intel Graphics 4000.
I have never heard of nVidia.com or AMD.com.
