Thanks for highlighting this. What type of file are you working on? What exactly happens when you move the cursor? Did it start happening after the update? It would be great if we could see what you’re seeing. Please post a screen recording of what’s happening, and we will help sort it out. Here are instructions for making a screen recording - https://bit.ly/3Fkf5Vd.
Thanks, Bill, for the video; sorry for the delay in reply. Have you tried resetting your preferences as suggested above? Go to Photoshop's Preferences > Performance, uncheck UseGraphicsProcessor, and restart Photoshop.
