We're sorry about the trouble with Photoshop. Please update Photoshop to the latest version (21.2.1) through the Creative Cloud desktop app to check if that helps.
Does disabling the Graphics processor from Photoshop help with the issue? Have you tried re-installing the Graphic card drivers from Nvidia's website to check if that helps? If not, please try that and let us know how if goes. You can also try disabling the option for Legacy Compositing by going to the Preferences for Photoshop, then Performance. Once done, quit and relaunch Photoshop before testing the app.
