Break apart drop shadow effect, select shadow image, apply Gaussian blur effect. I hate the way even 2019 renders the shadow. Not smooth...not smooth at all.
I believe 2019 has two options for the shadow tool, one of which is Gaussian blur. Perhaps it's not set by default?
Correct. I did not notice that before. However, If I want to make a white halo glow for letters it makes the glow much darker.
