Overview
Using the Show String Picture command seems to cause some errors with applying gradients to some fonts.

In this example we will use the open source .ttf font called Amaranth (https://fonts.google.com/specimen/Amaranth)

Turning off Character Shadows seems to make no difference.

When Character Gradation is on, the following issue occurs. Image on the left is RPG_RT.exe and the image on the right is Easy RPG 0.8 -- note the discolorations on the characters. (Example: the "y" in "Party" or the "g" in "Magic")

Turning off Character Gradation inside the the String Picture command produces a different look at the issue. Again, note the character discoloration such as "y" in "Party" or the "g" in "Magic"
