Photoshop + GPU = Black Screen
iMac (Retina 5K, 27-inch, Mid 2015) with AMD Radeon R9 M290 2 GB running Photoshop 21.1.1 Release and Catalina 10.15.3
Photoshop has a black screen unless I disable my GPU. Would prefer to use GPU for faster photoshop. Adobe tech support says I need to upgrade my GPU driver. AMD says it is part of the operating system. Help?
