such a blur is very blind for contrast, you can look at the panel on the right with this you need to do something in no other program did not notice this

Answer 1

And at what zoom do you get this blurryness?
The program is raster - at high magnification - blurit lines.
I'm using a graphics tablet - what is the degree of pressure in the settings? A hard degree to some extent can solve the problem.
