Photoshop Update? Why is it that when things aren't broken you think you have to fix it? I am paying a subcription for Photoshop and Lightroom and my screens show no buttons, fonts, or drop down menus. I am aggrivated with you people! What is the problem?!!? DAMN!
Now, a user will try to assist: First, try disabling GPU in the preferences (Preformance 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. Also see: https://helpx.adobe.com/photoshop/kb/acr-gpu-faq.html
