text in NVL mode is shown partially before being fully shown

Sorry if the title is confusing but I really don't know how to describe it.
Basically, the small part of the text is being shown before the scrolling/typing text effect is finished.
Hopefully, this picture will make it easier to understand!

(The "small part of the text that is being shown before the scrolling/typing text effect is finished " is in the red circles.)

Here's the related code:

Code: Select all

define v = Character(None, kind=nvl_narrator, what_xalign=0.5, what_size=60)

How do you fix it?
I tried changing the font's size but it didn't work.
Thank you so much!!
