This has been happening ever since I started using Photoshop 2019 instead of 2018. Sometimes when I am drawing on a layer it will pixelate and go out of wack, then the colors will get darker or lighter, then if I reset the layer it disappears but this happens out of nowhere. This makes it very difficult to draw at times.
