Why are there aliasing artifacts with my text?

Question

I am using a World Space Canvas, with a UI Text on it, using the Outline script, to produce the following text. I'm noticing a number of strange artifacts on the text, as seen below. Note for instance the yellow/black blog next to Tortuga, and the a in Tortuga not looking correct. There are others as well.

The same artifacts appear in my Scene view, so it leads me to suspect that it might be something Unity is doing that is odd. I've tried removing the outline, but I still see artifacts. Here is the text settings:

And here is the Canvas, which is the parent of the text:

Any idea how to remove these compression type artifacts? Thanks!

EDIT A few things tried:

1. Removed outline: See photo below.
2. Using an imported font with a high font size (64) set.
3. Changing the font size from low (1) to high(50) in the Text window.
4. Set all scaling to 1.

Answer 1

That is because the way the Unity Outline works, it will put a bunch of gross artifacts around your original text.

You can reduce the number of artifacts by raising your font quality, and making sure that you set the Outline alpha to 1.

Also try changing the Outline distance to negative values, which may help alleviate the artifacts.

Bottom line is, the Unity Outline implementation is pretty bad. I also stumbled upon this but I opted to not use it as it seems to be quite expensive in terms of CPU usage:

The Unity rendering issue was known to have issues, I reported this as a bug and it was accepted. The real solution is to use TextMeshPro, which Unity has since purchased, it is a much cleaner text rendering engine.
