Can't use Photoshop CC 2019. It's running really slow
Hello everyone. I am running on 5K iMac with macOS 10.15 Catalina (Intel Core i7, AMD Radeon R9 M290X GPU, Late 2014 model), but when I launch Photoshop CC 2019, app is running totally slow. I can't see cursor, and for example when I am typing any text, I can't see chars… it takes about 10 second until Photoshop shows me whole written text. Do you have any idea what can I do? I've tried to turn off "GPU" in Performance settings, but that doesn't help. It is really annoying, I can't normally use my Photoshop.
