Font size change for subtitles

Hello! I have a problem changing the subtitles size for my project. After feeding a lot of prompts including code, simple text prompts, it seems that the size of the subtitles won’t modify.

It seems like Gemini is actually considering the queries and actually makes the modifications in the code, but they won’t display on the screen as well.

I would like to know if there is any fix to this.

Thank you very much.
