Depends on what you're doing and how you're doing it.

Cornstarch is a pure starch with no protein or other ingredients. When
it gelatinizes, it's clear.

Flour has quite a few other things in it besides starch including
protein. When it gelatinizes, it's opaque because of the "impurities"
in it.

If you're making roux or slurries, they'll each behave differently.

What are you doing? How are you doing it? More info from you gets more
info.
