Image canvas flashes or flickers while making adjustments in Photoshop 21.2 on macOS 10.15.5
When I try to make adjustments to an image, e.g., brightness/contrast, exposure, etc., the image flickers as I move the slider up or down...very annoying and makes it difficult to see what I've done versus what was. I tried turning off the graphics processor to see if that would make it stop but it didn't. Any advice is appreciated. And FYI - I have macOS Catalina 10.15.5, the latest version of PS CC 2020, and just did the upgrade from Nik Collection 2 to 3. John
