So.... first problem is start menu witch os loading too long. Second problem - when you grab the canvas with hand and moving it by pen from graphics tablet it has a visible lag! When doing the same with mous everything is ok.... And the last one - from time to time when you enable/disable the layer visability the progam is freazing for some time. All а this is not appears on Photoshop CC 2019 at the same PC.
