Hi

Try enabling this option in preferences and restarting Photoshop to see if it helps

First, try disabling GPU in the Preferences (Performance tab). Any better?
If turning OFF GPU works, it's a GPU bug and you need to contact the manufacturer or find out if there's an updated driver for it. On the Mac, that's part of the OS update(s) so if this is the latest OS version, you may need to roll back a release.
