When I installed latest Crimson drivers 19.2.2. I noticed that occasionally I get artifacts on windows like black, blue or grey areas, depending on circumstances, covering menus, text etc. like there is lack of refresh of windows or something and if I use Ctrl+A or mouse cursor I expose content on covered ares like text on screen and similar.
I provided attachment with examples.
